摘要

水力耦合作用是岩体中力学过程与渗流过程相互作用的物理过程。水力耦合机理的理解是水力耦合分析的关键问题，其耦合机理是由岩体结构特性决定的。在分析岩体水力耦合过程基础上，根据岩体的基本结构及代表性单元体（REV）是否存在提出了建立水力耦合模型的方法。当裂隙岩体中不存在代表性单元体（REV）时，提出了裂隙岩体多重介质流固耦合分析的全耦合数学模型，给出流固耦合模型数值方法求解的数学模型及有限元计算表达式。程序编制和验证工作正在进行中。

Abstract

Hydro-mechanical(HM)coupling refers to the physical interaction between hydraulic and mechanical processes in rock mass. Understanding coupled mechanism is the foundation and key problem in HM coupling analysis. As a matter of fact

the coupled mechanism is determined by the behavior of rock mass structure. Based on analyzing HM coupling processes

the conceptual HM coupled models are proposed according to basic structure of rock mass and concept of representative element volume(REV). And than a multiple fracture media network fully coupled model of HM coupling is presented assuming REVS of fractured media without overlapping REV. Subsequently

a finite element formation of fully coupled HM model is presented to solve the mathematical model. The model and the formations will be applied to developing the program and software for HM coupling analysis. Numerical simulations program and validations of some samples are the subjects of ongoing research.
