Stability of rock slopes is generally controlled by the structure of rock masses, especially the soft structure surfaces. analysis of rock mass structures is a key to establish geological models and numerical simulation and a foundation to assess the stability of rock slopes. the weak structure surfaces are mainly bedding planes, faults, joints, schistosity plane and contact zones of intrusive bodies. since they are different in genesis and scale, the rock masses are different in features and mechanical intensities. based on the combination of rock structure bodies, 15 basic modes of deformation and failure of rock slope are systematically summarized. the deformation and failure of rock masses actually result from the recombination and rearrangement of these rock bodies. there are 11 types of rock mass structures and various deformation and failure of bank slopes are present in the reservoir area of the three gorge project
