摘　　要：针对影响水电站边坡稳定的因素存在明显的复杂性和模糊性,采用单一数学分析方法较难有效评价其稳定性的问题,根据水电站边坡实际工程特点,总结了对边坡稳定性分析具有重要参考意义的4类14项评价指标,建立了基于Fuzzy-AHP的边坡稳定性模糊综合评价模型。利用所求评价指标的隶属度和权重值,计算模糊综合评价矩阵,实现了边坡稳定性分级,并通过清江隔河岩水电站工程对所建评价模型合理性进行验证。结果表明:Fuzzy-AHP模型计算所得最大隶属度为0.5302,与之对应的边坡评价等级为稳定状态,评价结果与现场情况基本吻合,验证了所建模糊综合评价模型的准确性与科学性。该方法可为同类型地质条件水电站边坡灾害治理工作提供一定借鉴。In view of the obvious complexity and ambiguity of the influencing factors of hydropower station slope,it is difficult to evaluate its stability effectively by using a single mathematical analysis method.According to the actual engineering characteristics of hydropower station slope,4 types of 14 evaluation indicators with important reference significance for slope stability analysis were summarized,and a fuzzy comprehensive evaluation model of slope stability based on Fuzzy-AHP was established.Using the membership degree and weight value of the required evaluation index,the fuzzy comprehensive evaluation matrix was calculated to realize the classification of the slope stability level,and the rationality of the built evaluation model was verified through Geheyan Hydropower Station on Qingjiang River.The results showed that the maximum membership degree calculated by the Fuzzy-AHP model was 0.5302,and the corresponding slope evaluation grade was stable.The evaluation results were basically consistent with the site conditions,which verified the accuracy and scientificity of the built fuzzy comprehensive evaluation model.This method could provide a certain reference for the slope disaster management of hydropower station with same type of geological conditions.
