Abstract: Data related to geology, landform, property of rock and soil, and land use / cover types are selected to study the stability of reservoir slope based on RS/GIS and numerical simulation in this paper. The reservoir area is visualized for qualitative analysis. The dangerous zones are identified with a combined analysis of statistical evaluation, rule-based classification and numerical simulation of slope stability. The result shows that a combination of RS/GIS and numerical simulation is effective on the evaluation of the stability of rock slopes under complex conditions in the reservoir area.
