摘　　要：岩溶区堤坝帷幕在岩溶水侵蚀破坏下极易失效,合理的评估帷幕耐久性是保证堤坝安全运营的关键。为此,首先采用层次分析法(AHP)构建以设计因素层、施工因素层以及服役环境层的准则层,并通过相对标度计算出各指标权重;其次,运用模糊综合评价法(FCE)处理定性与定量指标值,构建了19个指标组成的岩溶堤坝帷幕耐久性评价模型;最后,采用所建立的评估模型对典型岩溶堤坝帷幕耐久性进行了综合评估。研究结果表明:模糊判断矩阵的特征值均小于0.1,说明各指标权重分配合理;典型岩溶堤坝帷幕耐久性综合评价结果代表值为0.5696,隶属优秀等级,说明该工程帷幕设计与施工方案可行,且帷幕目前运营状况与评估结果基本一致,即所建立的岩溶堤坝帷幕耐久性评估模型合理。研究成果可为定性化评价岩溶堤坝帷幕耐久性提供新思路,也可为岩溶区帷幕设计与施工方案、岩溶区建筑物耐久性、非岩溶区建筑物耐久性评价等提供借鉴。Dam curtain in Karst area is vulnerable to failure under Karst water erosion.Therefore,scientific evaluation of curtain durability is the key to the safe operation of dams.Therefore,this paper first used the analytic hierarchy process to construct the criterion layer of design factor layer,construction factor layer and service environment layer,and calculated the weight of each index via relative scale.Secondly,the fuzzy comprehensive evaluation method(FCE)was used to deal with the qualitative and quantitative index values,with the curtain durability evaluation model of the Karst dam composed of 19 indexes constructed.Finally,the established evaluation model was adopted to comprehensively evaluate the curtain durability of typical Karst dams.The results show that the eigenvalues of the fuzzy judgment matrix are less than 0.1,indicating that each index reports reasonable weight distribution.The representative value of the comprehensive evaluation results of the curtain durability of the typical Karst dam is 0.5696,which falls within the“excellent”grade.This shows that the curtain design and construction scheme of the project is feasible,and the current operation of the curtain is basically consistent with the evaluation results,that is,the curtain durability evaluation model of the Karst dam established in this paper is reasonable.The research results cast new light on the qualitative evaluation of the curtain durability of the Karst dam,and also provide a reference for the design and construction scheme of the curtain in the Karst area,the durability of the buildings in the Karst area,and the durability evaluation of the buildings in the non-Karst area.
