摘要

渗流模型是岩石流固耦合研究的一个关键问题。岩石在裂纹开始产生至裂纹充分贯通前，其渗透性质受内部孔隙和不断演化的微裂纹的共同控制。目前，岩石的渗流模型一般只是针对单纯的裂隙（或裂隙网络）或孔隙建立的，因此，不能很好地描述岩石裂纹扩展演化过程中的渗透性质和现象。针对这一问题，提出了岩石细观统计渗流模型，该模型将岩石裂纹演化过程中的渗透性视为一个非线性动态过程，同时，考虑了裂纹扩展演化和孔隙渗流的共同作用。因此，该模型可用于分析岩石裂纹扩展过程中的渗透性演化。

Abstract

Research on penetration model of rock is one of the most important subjects in coupled hydro-mechanical research. Penetration property of rock is controlled by pores and evolving cracks before the full coalescence of micro-cracks. The former penetration models of rock are set up just based on either crack or pore

so penetration property in the process of cracks spreading can not be properly depicted by them. In allusion to this problem

statistical penetration model is set up with rock damage evolution considered in this paper. The model regards the penetration property in the process of crack spreading as a nonlinear dynamic process

in which effects of both spreading cracks and pores in rock are jointly considered. Therefore

penetration property in the process of crack spreading can be perfectly expressed.
