THE F. E. M. ANALYSIS AND EXECUTION OF USED CLAY GEOSYNTHETIC-REINFORCED SOIL RETAINING WALL WITH RIGID FACING ON THE SOFT GROUND

Abstract

Geosynthetic- Reinforced Soil Retaining Walls with a rigid facing (GRS-RWs) can be constructed by many kinds of backfill materials. But, in fact the backfill materials of most constructions are the sandy soil.In Nagano, the JAPAN RAILWAY CONSTRUCTION PUBLIC CORPORATION are constructing Hokuriku-sinkansen car depot approximately about 100m wide and 2km long in use of GRS-RWs now. This construction has two special features, such as retaining wall on the very soft ground, the use of clay for the backfill material.The result of soil/water coupled F. E. M. deformation analysis and the execution of G RS-RWs are reported in the paper.
