摘　　要：针对现有相似性度量方法只能处理线性信息以及信息的非对称性所导致的尾矿坝风险评估效果差的问题,提出了一种基于柔性相似度量和可能性歪度的尾矿坝风险评估方法.将广义模糊数扩展为自适应模糊数,给出了柔性相似度量方法,并对其基本性质进行了证明;剖析各评估指标信息的非对称性,建立了可能性歪度矩阵;利用柔性相似度量和可能性歪度,构建尾矿坝风险评估模型,并通过尾矿坝实例来验证方法的有效性.Aimed at the poor risk assessment effect resulted from index information asymmetry and the fact that the existing similarity measurement method can only deal with linear information, this paper proposed a risk assessment method based on flexible similarity measurement and possibility skewness. First, a method for flexible similarity measurement was proposed based on expanded generalized fuzzy number as adaptive fuzzy number, and its basic properties were proved. Second, the asymmetry of the index informa- tion was analyzed, and a matrix of possibility skewness was built. Finally, a risk assessment model was established by using flexible similarity measurement and possibility skewness, and the validity of the method was proved by taking practical example of tailing dam.
