【 摘 要 】

The 3D finite element gird grid for whole pumped storage power station project area is set up. The seepage analysis shows the potential distribution for seepage field is clear and well. The leakage water flow form upper reservoir basin rack mass to underground powerhouse, and then to the lower river. The leakage has little influence on the hydrogeological conditions in the reservoir area. The anti-seepage and drainage measures is technically reasonable for upper reservoir. The permeability stability for upper and lower reservoir is acceptable. And grouting should be strengthened for the mountain in right dam shoulder should, if necessary according to geological conditions.
