金沙江向家坝库区长约１５０ｋｍ的沿江地带，共发育１０２个变形破坏体（含滑坡、崩塌和变形体），总体积１５．６５×１０８ｍ３．据统计岸坡变形破坏密度Ｄ和模数Ｅ分别达０．３４个／ｋｍ和５２４．９３×１０４ｍ３／ｋｍ．对崩滑灾害所处的环境特征研究表明，滑坡、崩塌与所在地层岩性、地质构造、地形条件、岩体结构特征及近期河流地质作用等环境因素共同作用有关．
A total of 102 deformation and failure bodies (including landslides, collapses and deformation bodies) have been developed along the Yangtze River with a length of about 150km to Xiangjiaba reservoir area in Jinsha River with a total volume of 15.65 × 108m3. According to statistics, the deformation and failure density D and modulus E of bank slope are respectively 0.34 / km and 524.93 × 104m3 / km. The study on the environmental characteristics of landslides shows that landslides and landslides are related to the environmental factors such as lithology, geological structure, topographical conditions, structural features of rock mass and recent river geological effects.
