Abstract：To study the deformation and stability in the condition of water level fluctuation and rainfall,the frame type model test was taken on the sliding body I of Majiagou landslide with a ratio of 1∶40.The shapes of sliding body and sliding zone in the front of the anti-slide pile were changed in the 2 .0 m×1 .0 m×1 .5 m frame to make sure that the stability coefficients were the same before and after being generalized.The reduction factors of the boundary thrust in the different water levels corre-sponding natural conditions were put forward.The rate of water level rise and fall was changed in order to guarantee equal sta-bility coefficients,and the numerical simulation results show that the rate of 0.7 m/d ranging from 183 to 204 m is in accord-ance with the actual landslide,and the rationality of the model is verified.
