摘　　要：裂隙岩体中裂隙发育规模和分布规律控制了岩体的渗流特性和变形规律,从工程角度出发,忽略岩块的渗透性,假设水流只在岩体的裂隙网络中流动,以立方定律为基本公式,给出了非平行楔形裂隙渗流方程,利用裂隙变形与渗透系数之间关系的耦合机理,给出了有限元分析模型。给出的算例表明,所提出的模型是可靠的。The developing scale and distributing law of fissures in fissured rock mass dominate the characteristics of permeating flow and deformation law of rock mass. Proceed from engineering viewpoints, the permeability of rock block is ignored. It is assumed that water flows only in the fissure network of rock mass, the cubic law is taken as basic formula, then the equation of non-parallel wedge-shaped fissure flow is given. Based on the coupling mechanism of the influence between fissure deformation and permeability coefficient , the finite element analysis model is provided. The calculating cases presented have shown that the presented model is reliable.
