A Study on Configulation and Hydraulic Conductivity of Rock Joints

On the basis of roughness measuring,aperture simulation, permeability test and numerical analysis using FEM,this paper deals with the cxnnplicated hydraulic conductivity of rock joints.The studies show that seepage in rock joints is obviously inhomogeneous, anisotropic and coupled with the joint deformation, and there is negative exponential relation between the hydraulic conductivity of a rock joint and the normal stress on it.
