| Abstract: | Based on saturated-unsaturated seepage theory,numerical simulation of ground water seepage in a anisotropic permeablity slope under persistent rainfall condition was studied by use of finite element method.The change law of pore water pressure and free water elevation is gained.The study can provide important basis for slope stability analysis and landslide prediction. |
