Research on Seepage of RCC Dams

Taking into account of the defect in the seepage analysis of RCC dams,in this paper the authors mainly adopt the aperture element without thickness model.By this model, the characters of these lift interfaces and lift joint interfaces are showed and the simulation of strongly permeable construction aperture and cracks is precisely done under the condition of the non increasing amount of nodes. The problem of seepage model of RCC dams is fundamentally solved. The results indicate that the solutions are reasonable as a matter of fact and the precision of solutions is enhanced.
