The geological condition of the upper reservoir for the said pumped storagepowerproject is complex, which has the outstanding problems in the reservoir bottom seepage. In order to solve the questions of reservoir formation and seepage, the overall anti-seepage scheme is used in the reservoir basin. Due to the great variation in thickness of the fill at the bottom of the reservoir as well as large and in-homogeneous settlement deformation of the back-filling, HDPE geomembrane is selected as the material for building the reservoir bottom seepage control system because it has strong adaptability to uneven deformation, which solves the reservoir seepage problem completely. The reservoir seepage is extremely low when completed, meanwhile, the anti-seepage scheme contributes a lot to reduce the construction difficulty, speed up the construction schedule and save the project investment. Design and application of geomembrane seepage control system are mainly introduced in this article, including selection and design of the material for the seepage control layer, design of peripheral connection of the geomembrane, and the geomembrane construction technology etc.
