摘　　要：针对单独使用熵值法确定各渗流指标权重存在的不足,使用层次分析法和熵权法结合方法得到各渗流评价指标的组合权重,建立大坝渗流基于组合权重的模糊物元模型,阐述了组合权重——模糊物元模型在大坝渗流性态评价中的工作原理,利用新建立的模型对老挝南欧江五级电站碾压混凝土坝7号坝段渗流性态进行综合评价.评价结果显示:南欧江五级电站碾压混凝土坝7号坝段渗流性态正常,评价结果与工程现状一致,该模型合理有效.In view of the defects by using entropy method alone,the analytic hierarchy process(AHP)and entropy weight method are combined to obtain combined weight of every evaluation index of seepage.The fuzzy matter-element model based on combined weights for dam seepage is established;and the working principle of combined weight-fuzzy matter model in dam seepage behavior evaluation is explained.The newly established model is used to comprehensively evaluate the seepage behavior of the No.7 dam section of the RCC dam of Nanoujiang Power Station.The evaluation results show that the seepage behavior of the roller compacted(RCC)dam is normal;and the evaluation results are consistent with the current status of the project.The model is reasonable and effective.
