Green energy technology: Study on anti-seepage technology of reservoir of a pumped storage power station

Abstract In this paper, the anti-seepage type design of the upper reservoir basin of a pumped storage power station is evaluated and selected comprehensively. Firstly, the importance, basic concept, classification and influencing factors of anti-seepage type design of the upper reservoir basin of pumped storage power station are summarized. Then, according to this project, three different anti-seepage design schemes for reinforced concrete panels, asphalt concrete panels, and a comprehensive anti-seepage scheme are put forward. The three schemes are comprehensively evaluated based on the analysis of the structural technical characteristics and the investment of anti-seepage technology. As a result, the solution combining a reinforced concrete panel on the bank with a geomembrane at the bottom of the reservoir is ultimately recommended as the most effective option. Finally, this paper gives the proposed results and puts forward the follow-up research and optimization direction suggestions to provide a reference for designing the upper reservoir basin anti-seepage type of pumped storage power station.
