Numerical Analysis of Saturated-unsaturated Seepage Problem of Anisotropic Permeability Slope under Rainfall Infiltration

摘要：

Permeability coefficient is a main factor effecting slope seepage field under rainfall infiltration. The heterogeneity of soil is very strong, as a result, the permeability of soil is anisotropic. Based on saturated-unsaturated seepage theory, the pore water pressure distribution of a slope having different ratios of anisotropic conductivity and different angles between its principal directions of hydraulic-conductivity anisotropic and horizontal direction are simulated using finite element method. The change law of pore water pressure under rainfall infiltration is gained. The study can provide important basis for slope stability analysis and landslide prediction.
