Geosynthetic-Reinforced Soil Walls and Slopes: Japanese Perspectives

The objective of this paper is to present a state of the art report on geosynthetic-reinforced soil walls in Japan. From 1996 to 2005, Japanese Geotechnical Society (JGS) has been in charge of the Technical Committee No.9 on earth reinforcement set up by International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE). This paper summarizes the current activities of geosynthetic-reinforced soil walls in Japan including design procedures and case histories. It is noted that most of the contents in this paper was prepared by the members of the Japanese Supporting Committee.
