Geosynthetic-Reinforced Soil Retaining Walls with a rigid facing (GRS-RWs)
can be constructed increasingly. The feature of the construction can use 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 shinkansen car depot approximately about 100m wide and 2km long in
use of GRS-RWs now.
This construction has three special features, such as retaining wall on the
very soft ground, the use of clay for the backfill material, and the use of
composited geosynthetics.
The result of soil / water coupling F.E.M. defromation analysis of GRS-RWs
are reported in the paper.
