为解决常规试验和工程类比法确定坝基岩体力学参数与实际情况不符的问题，提出基于粒子群优化算法（PSO）和ABAQUS的坝基岩体力学参数联合反演算法，给出该联合反演算法的具体实施流程并编制相应的FORTRAN计算程序，构建了坝基岩体力学参数的数学反演模型，实现了基于施工和运行期实测变形资料的坝基岩体力学参数 PSO-ABAQUS联合反演。算例分析表明，PSO-ABAQUS联合反演法简便易行、反演效率较高，是一种用于合理确定坝基岩体力学参数的通用方法。

Determining the mechanical parameters of a rock mass of a dam foundation using conventional tests and the engineering analogy method is not practical .To solve this problem, we proposed combined inversion of mechanical parameters of the rock foundation of the dam using the particle swarm optimization ( PSO) method and ABAQUS in this study .A mathematical inversion model of the mechanical parameters of the rock mass of a dam foundation was established .The implementation process was designed and the corresponding FORTRAN program was developed .The PSO-ABAQUS combined inversion of mechanical parameters of the rock mass of the dam foundation was realized on the basis of actual measured deformation data .The results of an example show that the combined inversion method is easy to implement and effective;it is a general method for reasonable determination of mechanical parameters of the rock mass of a dam foundation .
