基于组合赋权-物元可拓模型的滑坡稳定性评价OA

In recent years,disasters and accidents caused by landslides have caused great losses to people's lives and property.Therefore,conducting research on landslide stability evaluation is of great significance.This article selects 14 influencing factors such as slope height,cohesion,and permeability coefficient as evaluation indicators.Based on game theory,entropy weight and analytic hierarchy process are used to combine and weight evaluation indexes,and the evaluation model of landslide stability is constructed by matter-element extension method.Five typical landslides,including Fengjiawan landslide in Shiyan,Hubei Province,were selected to verify the model.The results showed that the evaluation results of the model are consistent with the actual situation.Comparing matter-element extension model with TOPSIS model and CRITIC model,it is found that matter-element extension model has the highest accuracy of evaluation results.The research results provide a new idea for landslide stability evaluation work.
