Abstract
A series of shaking table tests were conducted in a 1-g gravity field in order to evaluate the performance of the geosynthetics-reinforced embankment on liquefiable sand layers during earthquakes. Those shaking table tests focused their attention on the influence of the types of reinforcement and the existence of replaced gravel on the liquefaction-induced displacement of an embankment. The conclusions obtained from this study are as follows; 1) It is impossible to prevent liquefaction itself without replaced gravel layer. However, while the acceleration is small, the geo-synthetics reinforcement restrains liquefaction-induced displacement. 2) In general, by combining reinforcing with geo-synthetics and replacing with gravels, the embankments show high stability.
