Abstract

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 2.0m×1.0m×1.5m 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 corresponding natural conditions were put forward. The rate of water level rise and fall was changed in order to guarantee equal stability coefficients, and the numerical simulation results show that the rate of 0.7m/d ranging from 183 to 204m is in accordance with the actual landslide, and the rationality of the model is verified.
