With the development of geomenbrane, geomenbrane has been adopted in more and more hydraulic engineering as anti-seepage arrangement. A three-dimensional finite element model was built to analyze two different anti-seepage schemes for upper reservoir of a pumped storage power station. Under the reinforced concrete face slab & geomembrane anti-seepage scheme or geomembrane anti-seepage scheme, the seepage field and the seepage discharge of the reservoir were calculated and analyzed under normal conditions and local damage of geomenbrane conditions. It is shown that the seepage characteristic was obviously influenced by the fractured zone around right abutment. Moreover, based on the calculation results, seepage discharge under normal working conditions and local damage of geomembrane was analyzed and it was found out that both schemes were able to satisfied requirements of the reservoir under different conditions. After comprehensive consideration, it is recommended that the reinforced concrete face slab & geomembrane anti-seepage scheme should be adopted as the anti-seepage scheme of the reservoir.
