摘　　要：近年来,由滑坡造成的灾害事故给人民生命财产造成了巨大损失,因此开展滑坡稳定性评价研究具有重要的现实意义。本文选取坡高、黏聚力、渗透系数等14个影响因子作为评价指标,基于博弈论运用熵权-层次分析法对评价指标进行组合赋权,通过物元可拓法构建滑坡稳定性评价模型。选取湖北十堰冯家湾滑坡等5个典型滑坡实例对模型进行验证,结果表明:模型评价结果与实际情况一致;将物元可拓模型与TOPSIS模型、CRITIC模型进行对比,发现物元可拓模型的评价结果准确度最高。研究成果为滑坡稳定性评价工作提供了一条新思路。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.
