摘要：
Based on the theory of saturated-unsaturated flow, the transient seepage rule of the Huanglashi landslide induced by water in the Three Gorges Reservoir Area is simulated using the finite element method of Seep under the influence of reservoir level and rainfall, considering the factors including the landslide mass permeability, the rainfall intensity and the rainfall duration. The consequential seepage results are drawn into the Slope, then the stability coefficients of landslide in specific condition are calculated. At the same time, the influence of shear strength target of landslide mass on the stability of this kind of landslide is studied, too. The results of numerical simulation show that the shear strength target has a bigger influence on the estimation of stability of the Huanglashi landslide, compared with the landside mass permeability, the rainfall intensity, the rainfall duration and so on.
