Slope is one of the major geological disasters which affects the safety of human life and property. And rainfall is an important factor to induce slope damage. Based on the theory of saturation - non - saturation and slope stability, Geo- studio software was used to simulate the change of pore water pressure and safety coefficient at the exit of Tuanshan tunnel in Wuhan East Lake Tunnel under the action of continuous heavy rain at 3d300mm. And the stability of the slope is obtained. The results show that the infiltration of rainfall leads to the decrease of the pore water pressure, that is, the decrease of the suction of the substrate, the elevation of the groundwater level, and the decrease of the shear strength of the slope, resulting in the decrease of the slope safety factor. Damage, it is necessary to take protective measures and reinforcement.
