摘要：Impervious curtain and intensive drainage holes take important roles to control the seepage field in the foundation of dam such as that with fault for Chipwi Hydropower Station. The three-dimensional seepage field is modelled with finite element method, and the efficiency is analysed for impervious curtain and drainage holes to control the seepage field. The results indicate that the curtain with less permeability is more efficient, especially for the area with fault. Drainage hole spacing does not influence the seepage field greatly. While the drainage hole spacing is doubled, whole discharge increases but the uplift pressure still meets the requirement according to design code.
