Abstract: In this paper, the finite element software Geo-Studio was used to simulate and analyze the stability of landslides under weakened and unweakened conditions. The influence of parameter weakening of different rainfall types on the stability of Shuping Landslide was also studied. The results show that the water content of the slope surface varied with different rainfall types. Under the rainfall condition, the higher the rainfall intensity in the later period, the higher potential of the landslide instability. The appearance time of the parameter weakening effect was different. The concentration rainfall type and the rainfall attenuation type occurred in the middle of rainfall duration, the rainfall average type and rainfall increase type occurred in the later part of the precipitation.

Key words: type of rainfall, parameter weakening, slope stability, water content, rainfall intensity
