The Effect of Curtain Boundary on the Dam Foundation Seepage Control

Huo, Shao Jun / Tong, Fu Guo / Liu, Gang

The dam foundation seepage control is usually a main work of dam design. This paper presented the effects of different concrete curtain boundary conditions on the dam foundation seepage control through numerical calculation with the finite element method. The results show that the depth of concrete curtain strongly depends on the permeability of dam foundation. The middle of curtain should be deeper than its sides if the permeability of central riverbed is higher. Therefore the design of curtain should be based on the numerical analysis of the dam foundation seepage with different curtain boundary conditions in order to make sure the safety and economy.
