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.

Key words: rock structure, hydro-mechanical coupling, multiple-level fracture media
