Behavior of reinforced earth embankments on liquefiable sandy ground

Dynamic response of a reinforced embankment on liquefiable ground and the effectiveness of reinforcement in preventing a large deformation was investigated. In this study, a numerical simulation of liquefaction was carried out using an effective stress analysis, based on data from shaking table tests of a reinforced embankment using non-woven fabric on liquefiable ground. It was found that: 1) The effectiveness of reinforcement using non-woven fabric on the reduction in embankment subsidence is small. 2) Reinforcement using non-woven fabric can control the occurrence of tensile stress in the embankment to a certain degree, but further study is required in regard to the effectiveness of reinforcement in preventing the failure of the embankment. 3) Reinforcing the embankment into a single body would be effective in reducing the embankment subsidence.
