DEFORMATION MODE AND STABILITY OF LONGWANGPING LANDSLIDE

Hu Jing

Abstract

Longwangping landslide can be divided into the upper landslide and the lower landslide.Based on the engineering geological condition investigation,the deformation process is analyzed.The deformation and failure mode are determined.The upper landslide belongs to the pushing mode and the lower landslide is the pulling mode.With the unbalanced thrust transfer coefficient method,the landslide stability is evaluated both in normal natural state and the heavy rain conditions.Using the finite element method,the change regularity of the seepage field and stress field considering heavy rain is obtained.Then the influence by storm on the landslide stability is estimated.The result shows that under the normal natural condition,the landslide is stable.But under the heavy rainfall,Long-wangping landslide is in the less stable state.
