中文摘要：

在 Kansai 区域的可溶解的土壤上的一个地球堤基础的地震反应的案例研究，西方的日本被介绍。基于一为可溶解的沙和 Biot 校准了周期的 elasto 塑料的组成的模型动态联合理论，地震分析被使用一个动态有效压力执行在飞机紧张状况下面的有限元素方法。最近的设计研究为与可溶解的沙在浸透的沉积物上受到地震刺激的一个河地球堤详细被说明。堤基础的模仿的结果为水迫使的加速，排水量，和过量毛孔在液化期间被获得，它被认为为地震 geotechnical 设计产出有用结果。结果证明基础土壤到达一个充分液化的状态，高过量毛孔压力比率由于摇晃的地震来临到 1.0。在地震的结束，广泛的液化引起大约 1.0 m 在地球堤的冠的在脚趾和 60 厘米解决的侧面的传播。

英文摘要：

A case study of seismic response of an earth embankment foundation on liquefiable soils in Kansai area, western Japan was presented. Based on a calibrated cyclic elasto-plastic constitutive model for liquefiable sand and Biot dynamic coupled theory, the seismic analysis was carried out by using a dynamic effective stress finite element method under plane strain condition. A recent design study was illustrated in detail for a river earth embankment subjected to seismic excitation on the saturated deposits with liquefiable sands. Simulated results of the embankment foundation during liquefaction were obtained for acceleration, displacement, and excess pore water pressures, which were considered to yield useful results for earthquake geotechnical design. The results show that the foundation soil reaches a fully liquefied state with high excess pore pressure ratios approaching to 1.0 due to the earthquake shaking. At the end of the earthquake, the extensive liquefaction causes about 1.0 m lateral spreading at the toe and 60 cm settlement at the crest of the earth embankment.
