abstract="Based on the theory of unsaturated soil, seepage and stability of slope under rainfall infiltration are studied with finite element method. It is shown that the matric suction reduced by rainfall infiltration is the key factor which causes the slope stability decreased. Furthermore, the influence of different values of matric suction and different locations of cracks on slope stability is analyzed. Results show that the greater values of matric suction, the greater factor of safety (FOS) of slope at primary state of rainfall, while this effect will decreased with rainfall went on. It is convenient for rainfall infiltration with cracks, so the FOS decreased by cracks in general. The FOS controlled by downstream cracks of slope at primary state of rainfall, while the upstream cracks will become more important to FOS with continuous rainfall.<p />",
