Solid-liquid Coupling Mechanism Research in Seepage Field and Stress Field of Fractured Rock Mass

摘要

In this article, we use the porosity to express the effective stress of rock mass, and get the equilibrium differential equation on this basis, using equivalent continuum model and the finite element method to simulate the degree of coupling. In full consideration the interaction between groundwater and the rock framework and referring to the underground water solid coupling seepage flow mathematic model, based on finite element theory, we obtain the calculation method and the coupling method. These methods can real simulate groundwater seepage condition and have a great significance.
