摘　　要：基于模糊数学理论和层次分析法,从土石坝所具有的自然属性、社会属性和经济属性出发,充分考虑影响土石坝安全运行的各种因素或指标,给出了土石坝安全性态评价指标、评价原理和方法以及安全指标综合权重矩阵的概念和相应求解方法。经实际工程检测分析表明:采用多层次模糊评判理论进行土石坝安全综合评价是合理、可行的。Based on the theories of Fuzzy Math and Analytic Hierarchy Process（AHP）, originating from the natural, social and economic characteristics of rock and soil filled dam and adequately considering different factors or indexes imposed on the safe operation of rock and soil filled dam, the comprehensive safety assessment of rock and soil dam through using multi-stratum fuzzy evaluation has been conducted. Furthermore, the safety assessment indexes, the theory of assessment, comprehensive weighting coefficient matrix and solution method are also presented. From the practical measurement of rock and soil filled dam, multitratum fuzzy evaluation method which is used to assess the comprehensive safety is reasonable and feasible.
