近年来，数值计算方法引人岩层移动研究中，离散元等均取得了一定成果，但未能对覆岩移动破坏的动态全过程进行模拟研究。本文基于岩石介质的宏观非线性主要是由非均质性和各向异性造成的，应用新的数值计算方法，对来动引起岩体失稳破坏的全过程进行了数值模拟研究。
In recent years, some numerical results have been obtained in the study of rock movement by introducing numerical calculation methods, such as discrete elements. However, the whole dynamic process of overlying rock failure has not been simulated. Based on the fact that the macroscopic nonlinearity of rock media is mainly caused by heterogeneity and anisotropy, a new numerical method is applied to study the whole process of rock instability failure caused by incoming motion.
