| Abstract: | Based on the study of hydrogeological conditions of dam foundations and permeability characters of Guangzhao RCCD, three dimentional finite element model of seepage calculation are established with considering structures for seepage preventing and drainage system in dam body and foundation. The simulation methods of lamella element and drainage hole curtain are analyzed, and the seepage controlling in different cases are calculated with feasible methods. Through comprehensive analysis of the characteristics of seepage in dam body and foundation , the optimal schemes and reasonable suggestions for seepage controlling are proposed. |
