摘　　要：运用有限元理论从Ｎ－Ｓ方程（Ｎａｖｉｅｒ－Ｓｔｏｋｅｓｅｑｕａｔｉｏｎ）出发，研究了交叉裂隙水流的基本特征。通过有限元计算结果与传统网络水力学算法及实验成果的对比分析，论述了在裂隙渗流分析中，传统网络计算方法的近似程度完全能为工程要求所接受。网络裂隙渗流分析计算时。In this paper the behavior of intersection fissure flow is studied using finite element method to solve Navior Stokes Equation. Comparing the result of finite element method with that of conventional network hydraulics method and experiment results, it is demonstrated that the accuracy of conventional network method in analysis of rock seepage completely satisify the requirement of engineering accuracy. When analyzing and calculating the network rock seepage, it is not requisite to separately consider the deflection flow problem of crevice water.
