| Abstract: | For the residual soil slope and expansive soil slope under rainfall infiltration, the causes of reducing shear strength of their soil mass are analyzed. The current slope stability methods considering effects of rainfall infiltration are discussed. The equivalent cohesion of unsaturated soil based on unsaturated soil strength theory is presented, then the limited equilibrium method, such as Bishop method can be used conveniently under rainfall infiltration for slope stability analysis. |

| Keywords: | residual soil slope stability rainfall infiltration unsaturated soil equivalent cohesion |
