摘　　要：通过系统分析组合网格模型的计算原理,为达到计算收敛快且精度高的要求,提出结合FLAC3D和ANSYS两种数值软件的组合网格法对岩质边坡混凝土置换加固效应进行模拟求解,同时采用等效插值方法解决组合网格间边界不匹配的问题。实例计算结果表明,此方法适用于岩质边坡混凝土置换加固效应的研究,可充分发挥FLAC3D与ANSYS软件各自的功能优势,能减少建模工作量,节省模型计算时间。The principles of the composite grid method were systematically analyzed. In order to achieve fast convergence and high precision of calculations, a composite grid method of FLAC3D and ANSYS was proposed to simulate the reinforcement effect of concrete replacement for rock slopes. Simultaneously, the equivalent interpolation method was employed to solve the non-uniform problem of the boundary between thick and fine grids. The calculated results of a case show that the proposed method is applicable to research on the reinforcement effect of concrete replacement for rock slopes. It can give full play of the advantages of both FLAC3D and ANSYS, reduce the workload of modeling, and save computing time of the model.
