Finite Element Analysis of N-S Equation of Intersection Fissure Flow

In this paper the behavior of intersection fissure flow is studied using finite element method to solve Navior-takes 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.
