The 19th JOINT WORKSHOP HELD IN BANDUNG, Indonesia
27th to 28th February, 2018
Institute of Road Engineering in Indonesia (IRE) and NILIM have carried out joint researchof road and traffic fields. PWRI is also participating in the joint research as a cooperator ofNILIM.
The 19th Joint Workshop was held in Bandung, Indonesia by PWRI and IRE on 27th to 28thFebruary, 2018.
The activities of 19th Joint Workshop are the discussion on Tunnel and Underground
Structures.
1. Contents
Discussion on Tunnel and Underground Structures
PWRI and IRE have been creating "The guideline for auxiliary method of tunnel construction
at mountain area". In this workshop, the final discussion toward the completion of theguideline was conducted. After the publication of the guideline, the seminar for publicity isplanned in Indonesia.
And then, IRE and PWRI discussed new themes of research, as follows.
①Regarding "tunnel facilities"
PWRI advised IRE following matters;
・It is necessary to grasp the present state of Indonesia at first, for utilization of the technicalknowledges of Japan.
・IRE should conduct at first the measurement of the amount and composition of the exhaustgas from vehicles that are actually used in Indonesia.
In addition, PWRI explained how to confirm, for example, the actual conditions in the tunnel
after the road tunnel is serviced.
IRE agreed to carry out the above matters sequentially.
②Regarding "Shield tunnel method"PWRI offered some published literatures about past cases. Then, it was decided that IRE
will begin to select the matters which they require.
In addition, as a response to demand from IRE, PWRI explained the outline of Tokyo Outer
Ring Road, as the current work about shield tunnel method in Japan.
③Regarding "3- dimensional numerical analysis "Finally, IRE consulted about 3-dimensional numerical analysis for mountain tunnel which
they are trying now. Therefore PWRI advised them for some questions concerning setting ofconditions etc., in light of the knowledge of Japan.
In addition, on actual construction, the displacement of inside of the tunnel is important, thatis one of the determined indicators when we compare measured values and analysis values,therefore PWRI explained the measuring method and notes at the time of measuring for thedisplacement.

2. Reference (History of the Cooperation)
The National Institute for Land and Infrastructure Management (NILIM) and the Instituteof Road Engineering (IRE) renewed cooperation arrangement in Indonesia, February 2014.
Under this agreement, NILIM and IRE have been continually sharing research information
by jointly holding technical seminars and exchanging researchers to strengthen links between
both research institutes and to form international human networks, thereby to contribute thegrowth of Indonesia.
