Abstract: Shiliushubao landslide is an important part of Huanglashi landslide group,one of the largest landslides in three gorges.It is located on the north bank of Yangtze river,1.5 km east of Badong sity and 66 km upstream of three gorges dam.The displacement of the landslide became more and more visible in 1970s,has become especially apparent since the reservoir impounding.Based on the geomorphy,geology,and deformation-failure features of Shiliushubao landslide,as well as the slope movement monitoring dada of more than 10 years,the influence factors and the deformation development process are studied.The deformation development tendency was predicted by using the GM(1,1) model.This paper provides some useful data for the measures of landslide prevention and the design of landslide treatment.
