ABSTRACT
Many researchers had done a lot of work about the analytical method combining the calculation of infiltration with slope stability analysis. Based on Mein-Larson infiltration mode and the limited equilibrium method, a convenient and general analytical mode for the analysis of slope stability under rainfall action is set up. Landslides are widespread hazard in China especially in many mountainous and hilly regions subject to heavy rainfall. Besides, the initial water table in slope, the vegetation and waterproof on the slope surface, the depth of impermeable layers, the amounts of antecedent rainfall and the anisotropy of penetration also have a considerable effect on the slope stability under rainfall action. Landslide due to rainfall is a complicated problem related to weather, hydrology, geology and mechanics. Seepage force may be the important way to influence the slope stability under rainfall.
