Many water front structures were heavily damaged during the 1995 Hyogoken-Nanbu earthquake. Shaking table tests were performed in order to understand the mechanism of deformation in the reclaimed ground and to evaluate the potential of geo-synthetic reinforced caisson type quay wall. The conclusions obtained from this study are as follows: 1) While the acceleration is small, the geo-synthetics reinforcement restrains liquefaction-induced displacement. 2) By reinforcing the backfill ground in such a way that it is surrounded by geosynthetics and caisson, the movement of the caisson can be reduced effectively.
