| 摘 要： | 通过节理面粗糙度测量、张开度模拟、节理渗流试验及有限元数值分析,探讨了岩石节理复杂的水力特性。研究表明,节理渗流具有明显的不均匀性、各向异性及与变形耦合等性质,节理的渗透系数与法向应力之间呈负指数关系。

| Abstract: | 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. |

| Keywords: | rock joints roughness aperture hydraulic conductivity |
