A Message from the New President
We all benefit from infrastructure, so will our future generations. Infrastructure
cannot be established in a society where consumers put only their own interests
before the common good. During World War II, much of Japan’s infrastructure was
reduced to ashes. However, even in the post-war turmoil, the nation was still unitedby the strong willpower to realize democracy and redevelop infrastructure. A visionof a national land was proposed to provide a basis for nation-building, and theprogress of infrastructure development helped Japan achieve high economic growth
at a phenomenal rate.
Kiyoshi Kobayashi
106th JSCE President

It is said that we live in an age where we could live to 100. We are all extremely
busy with everyday life. However, it’s not that the length of the day has become longer to fit in all daily activities.
So, we seek to rationalize everyday life by outsourcing parts of work, house chores, child-caring, nursing,transportation, etc. However, we still have to manage time to do leisure activities and learning activities by ourselves.
Every effort must be made to ensure the efficient use of time through big data, AI development, automatic operations,linear Shinkansen trains and traffic technology development. There is only so much rationalizing effect technologies
can provide individually. However, by improving efficiency in many different fields, modern people can overcome
time constraints and therefore can still enjoy leisure and learning activities. IoT technology coordinates different
types of infrastructure into a cohesive system and brings efficiency to time management.
“What does ‘better society’ mean?” The Japan Society of Civil Engineers (JSCE) must make persistent efforts tofind the answer to this extraordinarily difficult challenge. Blessed with natural resources, the Japanese have built afine tuned, civilized society and have been on a steady path built on the importance of human relationships both
among themselves and with those of other countries. People should enjoy their lives while respecting that there is adiversity of values and lifestyles. This Japanese attitude towards the way of life is signaling the world a vision of“better society.”
I would like to conclude my message with my commitment to endeavor, together with everyone involved with JSCE,
to set a new horizon of civil engineering towards “better society.” I thank you all for your continuous support.

【Alumni of DOBOKU Series】“Always Grateful for Favors Received in Japan”
Guanlin Ye
Professor, Shanghai Jiao Tong University
Study and work in Japan
After completing the master degree in Tongji University, China in March 2001, I started
my PhD study at Yashima-Zhang-Sawada lab of Gifu University. I learnt the constitutive
model of soft rock and finite element method deeply. Then I obtained the PhD degree inMarch 2004 with a dissertation on “Numerical analysis on progressive failure of softrock slope due to heavy rain.” During the three years, not only in study, but also in
personal life, Prof. Yashima supported me so much that I could be able to concentrate on
study without suffering financial embarrassments. After graduation, I had worked at
Guanlin Ye

Geo-Research Institute (GRI) in Osaka for three years. Under the instruction of President Shanghai Jiao Tong
Prof. Adachi and Director Mr. Hashimoto, I conducted in the consultant jobs in University
geotechnical engineering. At the same time, I kept searching for approaches that can fill the gap between
academic theory and engineering practice. Influenced by the supervisors, I also had a dream to become aresearcher and an educator. Then in 2007, I returned to China and took a faculty position in Shanghai Jiao Tong
University (SJTU).

Build an advanced soil laboratory
Most of the underground construction activities in Shanghai were performed within the depth of 30-40m, wherea thick layer of alluvial soft clay was deposited. The soft clay has a large fraction of silt particles, high sensitivity
and strong nonlinearity. Thus it is necessary to apply a nonlinear numerical analysis with advanced elasto-plastic
model to simulate the related geotechnical engineering problems. In 2007, in spite of numerous undergroundconstruction projects in Shanghai, however, almost all the numerical analysis on these projects used the elastic
models or the simple elasto-plastic models, such as the Mohr-Coulomb model. Even in such situations, thematerial parameters were determined empirically. It has been widely recognized that precise soil testing date is
indispensable for the utilization of advanced elasto-plastic models. However, it was lack of qualified testing
apparatus in SJTU in 2007. I had conducted triaxial and plane-strain tests on soft rock samples in the third yearof

in

Gifu

With

the

and

experienceobtained during that time, I
reformed and upgraded an old
triaxial apparatus, so as toobtain the first set data ofconsolidated drained triaxial
test on Shanghai clays. This
became a trigger of launching a

Photo 1 Soil testing apparatus in Shanghai Jiao Tong University(small-strain triaxial, hollow cylinder)2

top level soil testing laboratory. In the past ten years, several apparatuses have been introduced into our lab,
including a small-strain triaxial test system, a small-strain true triaxial test system and a multi-purpose hollow
cylinder apparatus (Photo 1). All apparatuses are furnished with in-house developed measure & control program,so that they can deal with various testing requirements. Since I had been concentrated on numerical analysis
before returning to China, the knowledge on soil testing was limited. Prof. Yashima and Prof. Zhang havesupported me throughout these years. I appreciated their help.

Clarify mechanical properties of Shanghai clays and develop constitutive model
There were many underground constructions in Shanghai in recent years. However, the understanding of theground stayed in the compression index from oedometer and the shear strength from direct shear. First of all, I
and the students carried out soil tests to grasp the basic physical, chemical and mechanical properties of Shanghai
clays. Then we sorted out the depositional environments, and disclosed the relationship between the geotechnicalproperties and depositional environments. By using a thin wall sampler, we retrieved undisturbed samples atgood quality. Then conducted oedometer tests and triaxial shear tests to investigate the overconsolidation andstructural behavior of Shanghai clays. Recently, we began to measure the small-strain stiffness of the clays byusing the local displacement transducers. On the other hand, based on the Cyclic Mobility model proposed by
Prof. Feng Zhang of Nagoya Institute of Technology, we developed a modified elasto-plastic model that can take
into consideration of overconsolidation, structure, small-strain stiffness and the influence of intermediate
principal stress. We are proposing a systematic approach for numerical analysis, including sampling, laboratory
tests, constitutive model and soil-water coupled numerical analysis. We are trying our best to make it become astandard approach in Shanghai.

Stimulate technology and academic exchange between China and Japan
After returning to China, under the supports from Mr.
Hashimoto, director of GRI, I worked with theJapanese and Chinese experts to solve several
difficulttechnical

problems

encounteredinunderground space development in Shanghai. For
example, the construction management system forpreventing ground settlement induced by Double-OTube shield tunnel, the construction method of middle
wall for a metro tunnel with a large section, the design Photo 2 Interdisciplinary seminar on disaster prevention of heavy
and trial construction method of a flat and large
rectangular shield tunnel in Ningbo city. I also

participated the conferences between two countries, for example, China-Japan Symposium on GeotechnicalEngineering and China-Japan Conference on Shield-Driven Tunneling. In addition, I kept a close connection
with young Japanese colleagues. With the support of bilateral programs between JSPS (Japan Society for the
Promotion of Science) and NSFC (National Nature Science Foundation of China), collaborating with Associate
Professor Moriguchi of Tohoku University, we held an “Interdisciplinary seminar on disaster prevention of heavy
rain and earthquake” in Shanghai in 2015. About 70 participants joint us (Photo2). This kind of activities haveincreased the mutual understanding and promoted the exchanges between the two countries.
3It has been 11 years since I returned to China. When I take a look back, if it weren't the days in Yashima Lab and
GRI, I wouldn't become who I am today. This feeling is so strong that I would like to use SJTU’s university
motto “Always grateful for favors received” to close this essay.
Profile: Born in 1975. After obtaining PhD degree from Gifu University in 2004, he worked in Geo-Research Institute, then returned
to China in 2007. Now he is a professor at Shanghai Jiao Tong University.

《Column》Atsushi Yashima, Department of Civil Engineering, Faculty of Engineering, Gifu University
While Guanlin stayed in our laboratory in Gifu University, we had many foreign PhD candidates
from Africa and China. As Japanese undergraduate students were fully stimulated by foreign
students’ continuous research efforts, some of them decided to study in PhD course. Some ofJapanese PhD’s are doing research works in some universities in Japan. The research theme of
Guanlin was the numerical simulation of large slope failure due to heavy rainfall. I remember hewas working very hard to solve a very difficult engineering problem. I am very happy to know him
working as an active professor in Shanghai Jiao Tong University. I have been to Shanghai about 30
times. I hope Guanlin and I will carry out a new collaborative research work in the near future.

- Overseas Project Rapid Construction of Substructure and Superstructure work forthe longest offshore bridge in Viet Nam (Lach Huyen Port
Infrastructure Construction Project (Road and Bridge Portion))
This ODA project aims to provide access to Lach Huyen International Port (underconstruction) locating in Hai Phong, a city in the northern part of Viet Nam. The total
length of road and bridge is 15.6km, of which the bridge with length of 5.4km and widthof 16.0m is the longest offshore bridge in Viet Nam (Fig.1). Being in charge of thesubstructure and superstructure works of the bridge, we successfully appliedadvanced technologies and contrivance as described herein to realize the target of threeyear construction schedule.

1. Temporary Offshore Access Road by Using a Geotube Dyke
In a shallow area having with the water depth of around 2m at high tide, the temporary offshore access road wasconstructed by using geotube as a dyke (Fig.2). Enabling on-land condition of the site activities from piling work
to superstructure work, this road contributed significantly to shorten the schedule. Geo-tube is a close-ended
tubular fabric products with filling mouths at regularly spaced intervals. It is filled with a slurry mix of sand andwater. Water will dissipate through the permeable tubular fabric and out of the end filling ports that are left open
during filling work while sand will settle within the tube by gravity. Consequently, a structure with compacted
sand contained within a strong and durable fabric skin is obtained (Photos 1 and 2).

2. Steel Pipe Pile with Slip Layer as a Measure against the Negative Friction for the First Time Applicationin Viet Nam.
An adjacent area will be backfilled for future industrial zone. Ground settlement is expected, and consequently
down drag force (negative friction) will act to the pile during its service period. As a measure against suchnegative friction, Steel Pipe Pile with Slip Layer compound (φ0.8, φ1.1m, L=36～49m, total 1,128 nos) has
been applied (Photo 3).
In order to penetrate the pile through a stiff gravel layer to the bearing layer and shorten the schedule, the pilot
pile with the same diameter was driven by a vibration hammer supported by water jet. Then, the permanent pile
was driven by vibration hammer and finally by diesel hammer.
3. Steel Pipe Sheet Pile (SPSP) foundation as the second application in Viet Nam after Nhat Tan Bridge
SPSP foundation (φ1.2m, L=45.5m, L=47.5m, 58 nos per pier, total 3 piers) was applied to the main bridge withthe span length of 150m.
The construction period up to bottom slab was shortened from 9～10 months (achieved in Nhat Tan bridge) to
6 months thanks to the employment of the special CO2 gas automatic welding machine, the double tube method
to clean and fill grout to joint pipe, the combination of water jet and airlift pump during excavation work etc.

4. Span by Span (SBS) Erection Method with Span Length of 60m as the World’s Longest Class
The approach bridge with the length of 4.4km is a 5 continuous span PC box girder. In order to shorten theconstruction schedule, the segment was fabricated by short line match cast method (Photo 7) by controlling thedimension at 0.1mm accuracy upon taking into account the accumulative fabrication tolerance of previously castsegment and then, erected by SBS method. The necessary camber was also calculated and reflected to control
the elevation of each segment at fabrication stage and erection stage.
To maximize the capacity of 2 nos of huge scale erection girder (Photo 8), the pier head was precast, the safety
and moving device of the girder was improved, the segments were placed in advance on the surface of the accessroad (Photo 9). It enabled the completion of superstructure work within 13 months.

Student Voice“My New Life in the Land of the Rising Sun”
I am Osama from Egypt; I was born in 1991 in Egypt and raised in Kingdome of Saudi
Arabia. I graduated from Cairo University and I am a second year Master’s student under
the supervision of Dr. Kohei Nagai at The University of Tokyo. I would like to express
my deep gratitude to IAC of JSCE for giving me this opportunity to share my life
experience in Japan. Special thanks to JICA ABE Initiative for funding my study in Japan.
Without their financial assistance, it would be difficult to live and study in Japan With
the expectations for Japan-the land of rising sun, I came here at the end of August of
2016.

Osama Abdelfattah
HegeirThe University of Tokyo

Before my arrival in Japan, I did not know much about Japan, however, after my arrival,
I got tremendous support from JICA; they provided us with a two-week orientation program in which they
explained briefly the Japanese culture and how to live in Japan. I would like to mention that the Foreign Student
Office (FSO) of Department of Civil Engineering at the school helped me and continues to help me to overcome
all the difficulties I encountered, they helped me to find accommodation, open bank account, improve myJapanese, make more friends, and many other things that I do appreciate, special thanks to Mrs. Tonegawa of
the FSO, many things would be really hard to realize without her assistance.
I should say that my daily life was not easy without speaking Japanese; however, after I started my intensive
Japanese class at The University of Tokyo, I could feel how speaking Japanese can make your life easy andenjoyable. As a Master’s student, you almost spend your first year doing coursework, once you obtain 20 credits
in coursework, you start your research. In that department, you will never have any difficulty to find courses
with English as a medium of study, Majority of courses are taught in English. Unlike some other majors, in thedepartment, many Japanese students can speak English, this makes making friends easier.
Since I finished all my coursework one semester ago, I have been doing myresearch on “Safety Assessment of Damaged Suspension Bridges” in which
I am tackling a real case bridge in Myanmar. The interesting thing about myresearch is that I can feel its importance and how the research is beneficial
for society; our research results have a direct impact on the human beings,
which I do find my interest. I would like to thank Dr. Nagai for giving me
the oppirtunity to do such an interesting research, I also appreciate theWith Dr. Mizutani in Myanmar

assistance of Dr. Koji Matsumoto in this project, special thanks to Dr. Tsukasa Mizutani for his tremendous
support and being more than a teacher.

My Presentation in Yangon Technological University

During Our Investigation of Pathein Bridge

At the present time, I am living in an international
dormitory in Odaiba called Tokyo International Exchange
Center TIEC, the dormitory has students from all over theworld, more than eighty nationalities are living together
enjoying an international multicultural atmosphere. In the
TIEC, we do have many activities organized by TIEC staff;
they organize many events that can introduce the Japaneseculture and other international cultures of other students,
they also provide Japanese classes for those who areinterested in improving their Japanese. There are many

facilities in the TIEC such as a gym, a outdoor football court, an indoor football court, a volleyball court, abadminton court, and many other recreational facilities and I do join all those activities. Since I am a Muslim
and pray five times per day, I was surprised that the university provides Muslim students with a place where they
could pray and so was the TIEC. I do really appreciate how they respect our believes.
At the school, there is a host family program organized by thedepartment; the department assigns you to a host family. The hostfamily is an alumnus of the department. I applied for this programand I was assigned to an amazing host, whose name is Mr.
Tanaka.

We meet occasionally. Mr. Tanaka introduced me to

many new things in Tokyo. The department also arranges
meetings from time to time where we all get together and talk in

to join this program, experience the Japanese culture, and shareyour own culture. Special thanks to Mrs. Ayuko Akaike and Mrs.
Akiki Suzuki, who are key persons of this pregame.
One of the most convenient things in Japan is the transportation
system; I commute around one hour from Odaiba to Komaba,

Tokyo. It is also important to say that I like Japanese food very
much; I do enjoy Tempura, Onigiri, Ramen nooldes, and many other cuisines. I want to encourage all8international students to come and study in Japan. Japanese people are friendly, tolerant, polite, and helpful. It isa nice country, and I can say that I do love Japan. Finally, I want to encourage Japanese students to interact withinternational students and introduce the Japanese culture, not to be afraid because of your English ability. It
would enhance mutual understanding.
