Abstract: Jointed rock masses is characterized as equivalent continuum medium. A coupled fluid flow and elasto-plastic deformation model of rock masses with finite-length joints is presented, which emphasized the mechanical deformation behavior and its relation with permeability of finite-length joints. As an example, the model and FEM analysis is applied in seepage control analysis of Xiluodu hydraulic project. The results show that the coupled effect has unfavorable influence on the safety of dam and work of underground grottos.
