摘要

采用基于细观损伤力学基础上开发的RFPA2D数值模拟软件，用2种不同的岩石材料来组成7个不同岩层倾角的横观各向同性的岩石试件，通过单轴加载数值模拟试验，模拟横观各向同性岩石渐进破裂的整个过程，分析了岩层与最大主应力之间的倾角和强度之间的关系，讨论了不同岩层倾角的横观各向同性岩体的不同破裂模式及其破坏准则。

Abstract

Based on mesoscopic damage mechanics

numerical code RFPA2D is developed to simulate the failure process of seven transversely isotropic rock samples under uniaxial loading. The rock samples are composed of two different rock materials and they are formed with different dip angles between the rock layer orientation and the loading direction. Complete stress-strain curves are obtained and the deformation and failure behavior are described. As shown as the numerical results

rock layer dip angle of transversely isotropic rocks has much great influence on the failure process

such as peak strength

failure modes

and deformation characteristics et al. It is suitable to apply different failure criteria according to different failure modes caused by layer dip angle. The results of another serial of numerical simulations is well agreement with the experimental studies. The difference between the numerical simulations and experiments is probably caused by plane strain problems and parameters used in the simulations.
