Based on the theories of Fuzzy Math and Analytic Hierarchy Process(AHP), combining 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 earthfill dam, the general safety assessment of earthfill dam through using multi-stratum fuzzy evaluation has been established. Furthermore, the safety assessment indexes, the theory of assessment, comprehensive weighting coefficient matrix and resolution methods are also established. From the practical measurement of rock and soil filled dam, multi-stratum fuzzy evaluation method which is used to assess the comprehensive safety is reasonable and practical.
