Abstract:: Silver Creek nest landslide is located in the first community of Foshan village, Qingchuan County in Sichuan Province. Qingchuan is characterized as the old landslide of slip-bending failure formation. Recently, the landslide shows some signs of deformation. The sign is surface slumping. Because of 5·12 Wenchuan earthquake, the landslide showed the further intense deformation, forming a certain scale of inheritance circle arc-shaped crack in the middle of the landslide, which caused the landslide stability became worse, posing a serious threat to the life and property of the residents on the slope. According to the structure and deformation fracture characteristics of landslide, combined with geological environment, the resurrection mechanism of landslide was studied. The results show that landslide is less stable in adverse working conditions. Based on the above results, it is suggested to use the landslide treatment measures of ‘ntercepting water on the trailing edge+filling cracks+anti-slide pile in the front’ to control landslide.
