%X 连续介质力学模型较难模拟岩石类脆性材料在破坏过程中出现的非连续特性，离散元方法为解决这类难题提供了新的途径。如何准确反演估计岩石类脆性材料细观本构模型参数，已经成为制约离散元方法工程应用的瓶颈之一。系统评述了岩石破坏过程细观数值模拟方法，介绍了岩石宏观本构模型参数反演方法研究进展，讨论了岩石细观本构模型及其参数反演方法。岩石材料细观本构模型参数反演研究为离散元模拟从定性分析到精确定量计算奠定基础，也是进行岩石类材料破坏机理多尺度研究的前提。<br />
It is very difficult to simulate nonlinear characteristics of rock materials during fracturing process with continuum mechanics models. Discrete element methods supply for a new way for solving this kind of problems. However, how to precisely determine parameters of meso constitutive model of rock materials has become a key problem that affects the development and practical application of discrete element methods. Numerical simulation approaches for rock fracturing process are systematically reviewed. Estimating procedures for determining macro parameters of constitutive models of rock materials are introduced. Parameter inversion approaches of meso constitutive model for rock materials are discussed. The parameter inversion of meso constitutive model for rock materials can supply for foundations for precisely numerical simulation of discrete element methods and preconditions for multi-scale investigation of fracturing mechanism of rock materials.
