5. Objectives: (5 lines maximum)
The objective is to contribute to landslide disaster reduction along main transport arteries and on
residential areas through study on effective application of new technology on forecast,
monitoring and treatment of landslides in Vietnam and other areas in the Greater Mekong
Sub-region in close cooperation with Japanese universities and also ICL. The following targets
are expected: a) Development of Landslide risk assessment technology suitable for the targeted
areas in Vietnam. b) Capacity Development for research on landslide risk identification and
hazard mapping. c) Social application over the regions.
6. Study Area: (2 lines maximum)
Viet Nam , Japan , Countries in the Greater Mekong Sub-region (e.g. Laos and Myanmar)
7. Project Duration (1 line maximum)
5 years from March 2012 to March 2017
8. Report
1) Progress in the project: (30 lines maximum)
Total 45 (man x times) Japanese researchers visited Vietnam and investigated landslides in Ho
Chie Minh Route, Hai van Station, National Route No.6 and visited ITST in Hanoi. The Japanese
experts are landslide mapping (Headed by Miyagi), landslide monitoring (Headed by Ochiai) and
landslide testing (Headed by Sassa). We have selected a large-scale landslide including the Hai
Van Station which is the mid-station of Vietnam National Railway between the North and South
Vietnam as the pilot study site. We installed an extensometer in 2013 and made a plan to install
19 long span extesometer, one total station with 30 prism, and 3 static GPS (GNSS) and two real
time kinematic GPS and three drillings on the landslide. The first extensometer detected a clear
compression installed behind the railway station during rains in 2013. The length of landslide is
1.4 km, apparently reactivated type of landslides.
7 Vietnam engineers are invited to Japan by this project in 2012, 2013. They have entered in
Kyoto University, Tohoku Gakuin University, Shimane University, and Shizuoka university and
studying landslides as master or doctor course students. In addition to these invitation, 4
man/times were invited for 3 weeks in Japan.
As reported in IPL-157, the group has developed a new high stress ring shear apparatus (ICL-2)
to simulate the initiation and motion of megaslides with more than 100 m depth in 2012-2013.
The successful undrained capacity of ICL-2 is 3 MPa. The budget of development was prepared
by this project. As the first basic test, this apparatus was applied to samples taken from 1792
Unzen Mayuyama megaslide (volume is 3.4 x 108 m3, Maximum depth is 400 m) triggered by an
earthquake in Kyusyu island in Japan. The test result and performance was very satisfactory.
Then, the apparatus was applied for interpret the initiation and motion of the 1792 Unzen
Mayuyama megaslide. The test result and the computer simulation was very reasonable.
2) Planned future activities or Statement of completion of the Project (15 lines maximum)
The developed high stress ring shear apparatus will be applied in a mega-slide at Hai van Station
of Vietnam National Railway. In 2014, we will install 19 long span extesometers, one total
station with 30 prism, and 3 static GPS (GNSS) and two real time kinematic GPS (GNSS) and
three drillings at one site in the landslide and installed the inclinometers and pore pressure
sensors in three drilled holes.
We will organize a SATREPS session in the Third World Landslide Forum on 2-6 June 2014 in
Beijing. A SATREPS Workshop as the activity of this project on 28 July to 1 April 2014 in Hanoi.
In this workshop, all seven Vietnamese students will have oral presentation of their research.
3) Beneficiaries of Project for Science, Education and/or Society (15 lines maximum)
The subjects directly benefiting from the project's achievements include:
In Vietnam: people in 10 provinces frequently affected and the impact of the phenomenon of
landslides and a team of young engineers in the research institutes, universities and in technical
management agencies in local conditions better awareness in order to prevent landslides as
housing, farming and irrigation in mountainous conditions and applying appropriate technology
to actively prevent, mitigate consequences natural disasters caused by landslides. In Laos and
Myanmar: people in some mountainous locals and a division engineers in the agency and
management consulting. Results can be disseminated to other developing countries in the region
and the world to study and apply.
