Abstract: In this paper, we first analyze the typical rheological property of ordinary side slope rock soil medium, and use the three stage curve to describe the relationship between time and strain. Considering the difference to reservoir bank slope deformation slip and ordinary side slope, we established reservoir slope geological model by Flac3D numerical simulation software, and the related parameters and boundary conditions are also given by us. We found that there is a great relationship among water level variation, slope safety factors and rheological property of rock soil medium, we first make a preliminary presumption of this correlation. In order to check our preliminary presumption, what we have used is the cusp model of the nonlinear evolution mechanism of the slope of Professor Siqing Qin, Institute of Geology and Geophysics, Chinese Academy of Sciences. Through model calculation found that the final results are consistent with our preliminary presumption.
