An outlook on recent research and development concerning long-term performance and extreme loading

This report describes about researches and developments of geosynthetic-reinforced soil retaining walls which use short planar geosynthetic reinforcement and a continuous rigid facing. Static loading tests with small models, long term observation of fu]l scaled test embankments, static loading tests of full scaled test embankments, and shaking table tests were performed. The results of these tests showed that facing rigidity increases the stability of the wall remarkably. Considering these results, RRR method which is earth retaining wall with a relatively short geosynthetic and a rigid facing was proposed. RRR method has been used for important railway and road embankments and total length of the wall was about 50 km. During the 1995 Hyogoken-Nanbu Earthquake, RRR method with a total length 2 km performed very well, though many conventional masonry, unreinforced gravity-type retaining walls and modern cantilever reinforced concrete retaining walls were seriously damaged.
