摘要
This paper is based on the engineering geological condition investigation and analyzes the formation mechanism. A 2D model is developed. Considering landslide natural state and river trenching, three-simulations are done. The results show the following three points: 1) Baozha landslide is a pulling landslide.It is developed in easy-sliding strata-sandstone and muddy stone of Silurian System; 2) at present, the main factors that influence the deformation and stability of the landslide are the Laogouhe River cutting and rainfall; and 3) the Baozha landslide is stable now.
