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，应用新的数值计算软件ＲＦＰＡ（２Ｄ）——基于岩石宏观非线性行为可能是由具弹脆性特征的细观微元体不断破裂造成的，造成微元体不断破裂（并非某一时刻同时破裂）的原因是微元体材料性质（微元体强度、弹性模量和泊松比等参数）的非均匀性，是一个数学上相对简单但能充分考虑岩石介质复杂性的方法，对采动引起岩体失稳破坏的全过程进行了数值模拟研究，表明应用ＲＦＰＡ（２Ｄ）是切实可行的。
The macroscopic nonlinearity of rock media is mainly caused by the heterogeneity and anisotropy. The application of new numerical calculation software RFPA (2D) - based on the macroscopic nonlinear behavior of rocks may be caused by the meso-scale micro-elements The reason that the rupture of the body is caused by the continual rupture of the rupture of the rutile body (not at the same time rupture at the same time) is due to the inhomogeneity of the material properties of the body body (parameters such as micro-body strength, elastic modulus and Poisson’s ratio) The method which is relatively simple in mathematics but can fully consider the complexity of rock media, conducts the numerical simulation of the whole process of rock failure caused by mining. It shows that the application of RFPA (2D) is practicable.
