Reinforced Soil Structure

Geosynthetics reinforced soil retaining wallジオシンセティックス補強土擁壁

We are developing soil reinforcement materials to ensure high stability of the retaining wall with backfill against a huge earthquake. Recently, a square-shaped geocell has been developed, which shows a high reinforcing effect even on large-particle fill materials. Seismic performance of the retaining wall with the invented reinforcement material will be examined by pull-out test and shaking table model test.


Bearing capacity characteristics of geo-cell reinforced soil

When the geocell is laid on the foundation of the structure, it is expected that the vertical bearing capacity of the foundation will be improved. in order to investigate the bearing capacity characteristics of geocell-reinforced soil, a series of small scale model tests are being carried out together with digital image correlation.
