摘要
针对堤防工程的特点,根据安全评价指标构建原则,构建包含安全性、适用性、耐久性子目标及其影响因素指标集的堤防工程安全评价指标体系。为克服传统赋权法的主观随机性,引入信息熵理论确定各评价指标的熵权,构建熵权模糊物元堤防工程安全评价模型,并应用于工程实例。研究表明,熵权模糊物元分析法在堤防工程安全评价中有一定应用价值。
According to the characteristics of levee constructions ,the principles of safety evaluation indicators ,including safety ,applicability ,durability and its influencing factors were established .The evaluation system was aimed to overcome the arbitrariness of conventional weighting method ,and introduce information entropy theory that determines the entropy of each index ,so as to construct fuzzy matter element levee safety evaluation model based on entropy that can be applied on real-world engineering projects .These studies indicate that entropy fuzzy matter element analysis is applicable in the safety evaluation of levee constructions .
