为了进行渗流作用下的边坡稳定性分析，必须考虑 渗流场与应力场之间的相互耦合作用。目前对渗流作用下边坡稳定性的分析一般都是通过自 编程序进行的，通常都是先对渗流进行有限元数值模拟，然后再对边坡采用条分法进行稳定 性分析。目前国际上关于渗流作用下边坡稳定性的分析方法发展较快，已经可以采用有限元 强度折减法来进行分析计算，尤其是PLAXIS有限元程序对于这方面有较好的适用性。应用PL AXIS有限元程序采用有限元强度折减法，进行了渗流作用下的边坡稳定性分析，并用ADINA 和GEO -SLOPE程序进行了验算。  

To analyse the stability of soil slope under seepage, the effects of coupling between seepage and stress fields should be considered.Until now, the stability analysis of the soil slope under seepage is carried ou t through the program developed by the researcher. Usually, the data of seepage are simulated through FEM, then the stability is analysed by the means of slicin g. The analysis and calculation through strength reduction FEM is feasible. More over, the PLAXIS finite element program is suitable to this field. In this paper , the PLAXIS finite element program is adopted to analyse the stability of soil slope under seepage through strength reduction FEM. Then the checking computatio n is conducted through the program of ADINA and GEO - SLOPE.
