APPLICATION OF IMPROVED NODE VIRTUAL FLOW METHOD IN FINITE ELEMENT ANALYSIS OF SEEPAGE IN DENSE DRAINAGE HOLE CURTAIN PROJECT
Based on the nodal virtual flow method and the merits of improved cut-off negative pressure method in accurately simulating unsaturated action of elements in transition zone,this paper presents an improved nodal virtual flow method.This method can accurately simulate unsaturated effects,and also gives full play to the fast calculation characteristics of nodal virtual flow method.This method is applied to high RCC of Longkaikou Hydropower Station.In the finite element calculation and analysis of seepage in gravity dam and dam foundation,the precise simulation of dense drainage holes and curtains is realized,which provides a theoretical basis for seepage control design of the project.
