    • Abstract
  • The seepage control measures are the main items for the design of the dam and underground powerhouse caverns of Wudongde Hydropower Station. A refined 3D finite element model is established to simulate the complicated seepage control measures and geological conditions for the dam foundation and the underground hydropower cavern area at the right bank of Wudongde Hydropower Station. The numerical results show that the integrated measures composed of curtains and drainage hole rows will control the water flow from the reservoir and mountain area efficiently. The powerhouse cavern walls will be above the ground water surface. If the permeability is stronger along bedding in thick limestone and dolomite layer, the seepage control system will work more efficiently, but the flux from drainage holes increases obviously.
