摘要：Estimation of permeability in jointed rock mass is important to provide input parameters for numerical models simulating transient water flow. The influence of fractal distribution of rock joints on the permeability behavior of water transform is presented by using fractal geometry and Darcy's law. The self-similar property of fracture network is applied to quantitatively describe the fractal distribution of rock joints. Based on the parallel theory of network and Darcy's law, the effective permeability of jointed rock mass is proposed.
