- Abstract
There are many landslide disasters in China, especially reservoir landslide, which will cause huge disasters and losses once it is unstable. Therefore, stability evaluation is the primary premise of landslide prevention and early warning. According to the special geological conditions of reservoir-type landslide, four items, including structural characteristics, geological structure, deformation characteristics and hydrological conditions, were selected as stability evaluation indexes, comprising ten factors. The grade of landslide stability was divided, the evaluation index system was established and its weight was determined. Then the fuzzy comprehensive evaluation model was established by changing the weight according to the change of index data. Taking Baishuihe landslide in the Three Gorges Reservoir area as an example, the steps of fuzzy comprehensive evaluation with variable weight were discussed in detail, and the results are basically consistent with the actual situation of landslide. The example verifies the feasibility of the evaluation method and can provide reference for the evaluation and prevention of similar landslides.
