Abstract
To effectively grasp the deformation law of landslides,based on the results of landslide exploration,the deformation characteristics of landslides are analyzed first,and combined with the deformation monitoring data,the development trend of landslide deformation is evaluated through deformation prediction.The analysis results show that the deformation characteristics of a landslide in Nanchong,Sichuan province are relatively significant,mainly manifested as a large number of surface deformation cracks,and the measured deformation amount is relatively large,and the deformation is also characterized by continuous change,It is concluded that the deformation of the middle part is relatively the weakest,the deformation of the front and rear edges are relatively large,and the deformation of the front edge is relatively slightly larger.The landslide has a great risk of instability under unfavorable working conditions.Meanwhile,according to the deformation prediction,the subsequent deformation of the landslide will continue to increase,and the maximum value can reach 289.11mm,and the subsequent stability of the landslide will tend to be further weakened.Considering the current stable state,it is suggested to carry out the landslide prevention and control research as soon as possible.关键词
