Deformation Process of Thrust Load-Caused Landslide on the Basis of Deep Displacement Monitoring

According to the surface displacement of the Zhang Jiawu landslide in Badong County,this paper revealed that the main factor affecting landslide deformation is rainfall,and sliding soil deformation is later than the rainfall,and the lag time is progressively larger from the trailing edge to the leading edge of sliding soil.Meanwhile,by the FLAC,the paper simulated the deformation process of the Zhang Jiawu landslide in gradually saturated weight of sliding,and obtained the same results as those encountered in the actual situation.
