IAC News No.57【Alumni of DOBOKU Series】“Civil Engineering Can be a Bridge Between Japan, China, and
the World !”Xianfeng Ma
Associate Professor, Tongji University, China
Study in JapanMy study in Japan started in 1997 when I was enrolled as an exchange student at Osaka
City University due to a student exchange program with my home university Tongji
University in Shanghai, China. I continued my studies at Tokushima University thefollowing year and then worked as an assistant professor there for more than two years
before shifting to Geo-Research Institute based in Osaka as a researcher. During my sixyear stay in Japan, I was privileged to have the chance to study geotechnicalengineering, communicate with the local people and make friends, enjoy Japaneseculture, about which I am very pleased to report and share. The title of this report was

Xianfeng Ma

actually inspired by the lyrics of the anthem of the Department of Civil Engineering in Tokushima University,
which encourages civil engineering students to aim high and think big even as to dream of building a bridge
between Japan and China.
When it comes to communication in civil engineering between Japan and China, the history is so long that it canbe dated back to Sui or Tang dynasty which was more than 1000 years ago when Ganjin Monk and Master
Koubou introduced ancient Chinese construction technologies into Japanese society. The history contains
numerous activities and events, with which personal experiences can never be compared. However, I am sure
my beginning of studying in Japan was somehow inspired by such a history so that I think maybe I could bringback some new technologies from Japan as a result.
On Day 1, after I arrived in Osaka, I got a real feeling of the high level of Japanese civil engineering. Seeing
from the airplane when approaching Kansai International Airport, the reclaimed island seemed to be floating in
the blue sea of Osaka Bay. The structures on the island and the bridge connecting the land and the airport wereboth beautiful and futuristic to me. After my supervisor, Professor Akitoshi Mochizuki, came to pick me up at
the airport, I was deeply impressed once again on the way to the city center, seeing the advanced highway system,
congested buildings and infrastructures, all looked shiny and new.
In the soil mechanics laboratory in Osaka City University, I was lucky enough to meet outstanding academic
staff and research students who had very unique characters in their pursuit of knowledge and I enjoyed studying
1and living there. I also understood that the geotechnical centrifuge in this lab, developed by Professor Masato
Mikasa in order to verify his consolidation theory on soft clay, was actually the first one in Japan. A well-known
episode is that coincidently, Prof. Andrew Schofield independently developed a similar facility at almost thesame time in the UK, which is almost on the other side of the planet. It is more interesting, as a later developmentin 2008, that I actually got a chance to study at Cambridge University for one year which enabled me toexperience both of the two legendary centrifuge facilities. During my time in Osaka City University, there werealso hot discussions in various seminars related to constitutive model research, effective stress principle and total
stress method, all of which are fundamental researches for practice in geotechnical engineering. As a result ofsuch experiences, I could understand the reason why civil engineering in Japan is so advanced.
When my advisor, Prof. Mochizuki, shifted to Tokushima University, I also moved to Tokushima city from mysecond year in Japan, a city featured by beautiful mountains and a long coastline. In their geotechnicalengineering group, a lot of activities had been carried out related to development of centrifuge and shear test
apparatus and numerical analysis using FEM, the involvement of which benefitted me a lot. In addition, I joined
a number of local activities, the most important one of which is Awa Odori dance festival, a famous andtraditional matsuri (festival) in Japan. The experience of Japanese culture and good relationship with Japanese
students also helped me enjoy my time in Tokushima during my four-year stay there.
My PhD thesis was on the seismic response of underground structures (including the analysis of the failure
mechanism of Daikai subway station which collapsed in the 1995 Kobe Earthquake), which is one of many
advanced fields in Japan. However, at the time, that topic was not paid attention to back in China and suchresearches had yet to be carried out. It was my Chinese supervisor, Prof. Linde Yang, who advised me to take it
up as my thesis theme, and considering the later development of research in China, I appreciate him very muchfor his good selection of the topic for my PhD study, and thanks should be given to him for his foresight.
In 2002, I got a chance to further my research in the Geo-Research Institute in Osaka under the president
Yoshinori Iwasaki. I carried on studies about excavation works using FEM. During that time, I also joined in a
project commissioned to GRI which is on the risk assessment of the Yangtze-River underwater tunnel inShanghai. Also, I visited Naruo Research center of Toyo Construction group and gained some experiences with
their centrifuge modeling for a short time.
Back to China
In 2003, upon the recommendation of Prof. Hehua Zhua, I came back Tongji Unviersity and joined theDepartment of Geotechnical Engineering, working on the construction of a geotechnical centrifuge laboratory.
Centrifuge modeling in China started in the 1980s and no more than 10 facilities had been built up until 2003.
With the help of Prof. Mochizuki, Prof. Naotoshi Takada, and Mr. Tatsuo Miyake, who had a lot of experiencesin centrifuge modelling and worked as external advisors for Tongji University, the facility was completed at theend of 2006 and has been in operation since that time serving for the research of all academic staff in thedepartment. The development of the centrifuge at Tongji University kicked off a new boom of centrifuge
construction in Chinese universities. Last November, we hosted the 2nd Asian Conference on Physical Modelingin Geotechnics (Asiafuge2016), and luckily attracted 120 attendees, one third of whom were from Japan.
In the time of my returning to China, the construction of metro network in the cities of Beijing, Shanghai etc.
started to see a speedy development, as well as some accidents as a result of failures in risk management. Among2the accidents, the collapse of the Shanghai Metro Line No. 4 has been reported widely, featured by thecomplexities and difficulties of restoration of structures. In the repair works, advice from Japanese experts,
headed by Mr. Tadashi Hashimoto of the Geo-Research Institute played a very important role, and Japanesetechnology and experience were introduced and contributed to the successful restoration work. Whileparticipating in the whole process of communication between Chinese and Japanese experts relating to thisproject, I saw Japanese technology and experience in civil engineering practice earned trust among local
engineers. At present, the metro system is still under construction, especially in big cities like Beijing andShanghai. Also, urban infrastructures and underground space constructions are sure to continue, thus there will
be much chance and many places for new technologies developed in Japan to be introduced in China andcontribute a lot to these constructions.
Envisioning the future
One thing I came up with in my mind during the time
I spent studying in Japan is that technology should
be shared beyond regions and countries, developedin the way of communication and collaboration.
Recently, there has been a lot of communications andcollaborations between China and Japan, i.e. ChinaJapan Symposium on geotechnical engineering,
China-Japan Symposium onshield tunnelingtechnology (chaired by Prof. Jun Koizumi of Waseda
University), student workshop between Nagasaki
University and Tongji University, many of which I
am still involved in. Furthermore, it is also necessary

Tongji University delegates (Leader: Prof. Huang Hongwei)
visiting to the centrifuge facility at Tokushima University

to establish more communication mechanisms
among Asian researchers and engineers, and with theprogress of globalization, it is in the high interests of the civil engineering community to develop communication
platforms both regionally and on a worldwide scale. With this in mind, civil engineering can be a bridge between
countries and beyond. Finally, I would like to take this opportunity to give my sincere thanks particularly to mysupervisor, Professor Mochizuki, without whom all these things could not have happened. I also want to thankall the people I met during my study and work in Japan who were very helpful and supportive without reservation.
Thank you very much.

Profile: He came to Japan in October 1997, and studied at Osaka City University and Tokushima University, completed his PhD
dissertation at Tokushima University (degree was awarded from his home Tongji University). He worked as an assistant professor
at Tokushima University and an researcher at Geo-Research Institute and returned to China in 2003. Now he is an associate
professor at Tongji University and the head of geotechnical centrifuge laboratory.

Dr. Cai Min, who was the first international PhD student, who came from Tongji Univ., P.
R. China in my laboratory, and opened a way for an academic exchange program between
Osaka City University and Tongji University in 1991. The agreement allowed Mr. Ma
Xianfeng, a student of the latter university, to come to study geotechnical engineering inJapan in 1997 supported by scholarships from the Heiwa Nakajima Foundation and theFoundation of Wesco Co., Ltd.. After he studied at Osaka City University for six months,
he moved to Tokushima University following me as I got a professor position at that
institute.
He carried out researches on the failure mechanism of Daikai underground station(Kobe kosoku line of Hanshin Railways) which was badly damaged during the Kobe earthquake of 1995. He
introduced the new concept "relative displacement between structures" in the failure mechanism, and hesucceeded in explainning the failure process of center columns of the station during the earthquake
splendidly. Though a paper on the failure mechanism was presented in China, I believe it would be of greatinterest to present it here in Japan, too. He completed his PhD dissertation at Tongji University in 2000.
After he supported activities of my laboratory for two years as an Assistant Professor, he experienced
consultant works at the GRI, Osaka for one year. Then, he received an associate rrofessor poisiton in Tongji
University and he returned back to China in order to establish the Geotechnical Centrifuge Center of Tongji
University.

The JSCE IAC Special Seminar“The Project of Lyon-Turin Railway Tunnel”
1

Introduction“The Mont Cenis Base Tunnel & the Lyon-Turin railway
link” was reported by Tunnel Euralpin Lyon-Turin(TELT), which is a public organization of the project
management, on April 5th, as a JSCE IAC Special
Seminar. Mr. Jean-Fracois Corté, Chair of TELT
Commission, Mr. Marurizio Bufalini, COO, and Mr.
Alessandro Jannetti, CFO, and other two executives of
TELT presented following topics: 1) Organization of
TELT, 2) Main points of the project, 3) Comparison of
the famous Gotthard Base Tunnel and other base tunnels

Mr. Bufalini, delivering a presentation on the projectin the Alps. About 50 participants had a significant 2hour seminar including Q&A sessions, understanding importance of railway link project in EU.

Organization of TELTThe Lyon-Turin Railway Link project had been recognized its importance for French and Italy, and the Mont
Cenis Base Tunnel had been a key project for the railway link through the Alps. The two governments made anagreement for the promotion of the project, and a new organization which was responsible for the realizationand management of the new railway infrastructure was founded in 2001 by two countries’ public funding. Thenthe organization was named as TELT in 2015.
There are 110 staff in TELT, consisting of professionals in engineering, finance, contract, and general affairs; 56
4persons come from French and 54 from Italy, 55 persons are males and 55 are females.
The project was approved as an EU co-funding project due to a important and significant railway link in the
major southern nations of the EU. TELT will plan to launch the tendering process for the main construction
works in 2018, and the railway is scheduled to open between 2029-2030.
This visit and presentations were planned to promote the understanding of the project and to call for tenders
among Japanese construction firms and related firms and engineers.

Main points of the project* Length of the railway link between Lyon and Turin: 270km* Length of the tunnel (Mont Cenis Base Tunnel): 57.5km (78% of the tunnel is located in France and 22% in Italy)* Section of the tunnel: two single truck tunnels* Vehicles: high-speed passenger train, regional trains, and freight trains, maximum operating speed will be
220km/h* Tunnel construction costs: 8.6 billion euros (euro 2012, constant prices)* Financing: total costs are burdened by EU 40%, Italy 35%, and France 25%.
* Periods of studies and design: 2014-2018* Planned schedules: civil works in 2018-2027; installations in 2026-2028; operational testing in 2029; operation
start-up in 2030
* Geological overview: the Alps in which the tunnel is located, were formed as a result of the collision of theAfrican and European tectonic plates. Due to this geological characteristic, thegeological zones of the project are not clearly separated, i.e., the tunnel is built in ageologically complex region. Based on RMR Index (Bieniawski 1989), the quality ofrock masses is excellent: reaching 90, and very abrasive, strong and hard (250Mpa
uniaxial compressive strength).
* Excavation methods: TBM (Tunnel Boring Machine) and traditional NATM
* Calls for tenders: 7 lots in France and 6 lots in Italy, and schedules for tenders and approximate contract fee
are explained.

Structure of International Affairs Division

ScientificExchange Fund are the two major committees serving the International Affairs Division. The former committee
supports the activities of the JSCE within the ACECC, which was established in 1999 with the JSCE being a
6

founder member. The latter was inaugurated in January 1989 and is responsible for the selection of grantrecipients from the “JSCE International Scientific Exchange Fund Charitable Trust” and it cooperates with the
Research Committee, the JSCE led Technical Committee (TC) within the ACECC and the International
Communication & Collaboration Group etc., supporting the international activity of the JSCE in Bilateral /Multilateral Technical and Academic Exchange Support Projects, the establishment of bases overseas and thestimulation of business etc.
The International Chapter comprises nine overseas sections. The overseas sections are made up of both JSCE
members and “Associate Members”, newly introduced in April 2016, who reside in the countries and regions
where the sections are established.
Activities of the International Activities Center
Since its establishment in April 2012, the “International Activities Center”, which aims to support
internationalization of the civil engineering community, has been expanding its activities both in Japan andoverseas based on the following four policies.
1) Expansion of international networks and implementation of strategic bilateral exchanges
2) Dissemination of information both internationally and domestically3) Fostering human resources and supporting internationalization within Japan
4) Providing a place to resolve mutual problems
In its sixth year since establishment, each of its groups will continue to work based on their respective actionplans with regard to international exchange and collaboration, exchange of information with other countries,
improving the skills of engineers and fostering human resources, support for foreign students etc. Additionally,
International Round Table Meetings (RTM) etc. will be planned and implemented at annual meetings under the
direct management of the International Activities Center.
(1) International Communication & Cooperation activities
Concerning international communication and cooperation activities, bilateral exchanges will be advanced bysending groups of representatives to the overseas academic annual meetings of ASCE, KSCE, CICHE, MACE,
PICE etc., as well as collaborating with the Committee on the ACECC and the International Scientific Exchange
Fund Management Committee to hold symposia and seminars etc. Further, while strengthening cooperation withoverseas academic bodies in the West, we will promote a more multilateral form of international activity.
Concerning the overseas sections, the Associate Members assist in expanding branch activities and increasing
interest in Japanese civil engineering in those countries, so we aim to expand associate membership and increase
the number of advocates in overseas sections, thereby supporting the formation of people networks. Further,overseas sections work as points of exchange for engineers from the respective countries and those in Japan, andwe will support them in expanding the dissemination of information concerning Japanese civil engineering.
Concerning the ACECC, for which the JSCE serves as a secretariat, and looking towards the 8th Civil
Engineering Conference in the Asian Region (CECAR 8) to be held in Tokyo in April 2019, for which thissociety will act as host, the CECAR 8 Organizing Committee established within the JSCE will continue
preparations principally through its four subgroups (Planning, General Affairs and Finance, Academia, Events).
Further, we will actively aim to secure external funds for the purpose of enhancing the above-written meeting.

(2) Activities for the dissemination of information
Concerning our activities for the dissemination of information, and considering both the needs of members andmovements in the civil engineering field, we will maintain “International Activities Center Communications”
and our journal “International Activities Center News” as monthly publications, and aim to enhance the contentsof the English language website. Further, we will make greater use of Facebook for the timely dissemination of
information.
(3) Educational activities
Concerning our educational activities, the “Global Vision Symposium” which presents the current state of theoverseas construction business along with overseas enterprises and their strategies, and the “Japanese Civil
Engineers the Global Leaders Symposium Series” is growing as core projects of the International Activities
Center, and will continue selectively addressing themes with consideration of trends and concerns in the civilengineering community. We will also work on the production of an “Infrastructure Archive”, which was
originally begun with the JSCE centennial anniversary project, and which will be presented on the website,
introducing actual examples of Japan's international collaborations and contributions to the development ofoverseas infrastructure.
(4) Support for foreign students
Along with continuing efforts in building a foreign student network, we will hold the “International Summer
Symposium”, and arrange corporate briefing sessions and site tours to provide foreign students in Japan with
opportunities to present research and exchange information with each other.
Many of the miscellaneous activities described above depend on voluntary activities of our valued members, andwhilst we are continually reviewing the means to enhance the presence of the JSCE overseas, how to bridge thedivide between our ideals and reality is an ongoing issue. We would like to ask all our readers for theirunderstanding and support.
