【 摘 要 】

The safety of the reservoir construction and the normal reservoir as well as the normal operation of the power station is affected by the phenomena of reservoir bank slopes' instability and failure. Nowadays there is a lot of research about plain reservoir bank collapse, but the research about mountain valley reservoir bank collapse is not very perfect. Because of the various material characteristics and complex structure of mountain valley reservoir bank collapse, the influencing factors, mechanisms and types of mountain valley reservoir bank collapse is complex. According to a mountain valley reservoir site in southwest China, the bank collapse influencing factors are summarized, which are the formation lithology of the bank, the topography, the geologic structure, the hydrodynamic condition of the reservoir and the wave effect. The sensitivity of impact factors of the bank collapse is achieved by the orthogonal analysis. By contrast to single factor sensitivity, the cohesion in natural state and the wave height are the main impact factors.
