This paper, in the light of the special geological environment and actual project situation of the three gorges reservoir area, puts forward a comprehensive analysis and evaluation system suitable for the stability analysis of the bank landslide of the three gorges reservoir area under the premise of thorough consideration of the water influence on the stability of the bank landslide, and obtains the following achievements in several aspects that have the practical application significance and certain scientific research value : ( 1 ) it is discovered that the water activity is the primary factor of the formation of the new landslide and the revival of the ancient landslide. on the one hand, the rising underwater level reduces the actual stress of landslide ; on the other hand, the long time soaking of the underwater reduces the mechanics intensity of the landslide and the slide belt, both of which reduce directly the landslide stability ; ( 2 ) in view of the special condition of the three gorges reservoir area, this paper analyzes systematically the forces acted on the landslide of the three gorges reservoir area and the force varieties acted on the divided landslide when the water level changes between 175 meters and 145 meters. thus it is more scientific and comprehensive for the analysis of the forces acted on the landslide ; ( 3 ) this paper summaries systematically 10 kinds of typical computation projects by organic combinations of different kinds of situations in the dry season ( nature statue ), rainy season ( rainstorm or rains for a long time condition ), with 175m water level in the reservoir, during the earthquake, with the water level of the reservoir adjusted from 175m to 145m and so on, and produces
