Abstract
In response to the challenges of high seepage risk in the lower reservoir of a pumped storage power station located in an intensive karst development area and the difficulty in implementing vertical anti-seepage measures,this study takes a specific pumped storage power station as the engineering background to conduct research on optimizing anti-seepage schemes for the reservoir basin.A comprehensive comparison was made among three schemes from six dimensions:topographical and geological adaptability,material source conditions,anti-seepage performance,construction conditions,operation and maintenance convenience,and economic efficiency.The three schemes are:a full reservoir basin reinforced concrete face,a full reservoir basin asphalt concrete face,and a composite anti-seepage scheme combining an asphalt concrete face on the reservoir banks with a geomembrane on the reservoir floor.The results indicate that the composite anti-seepage scheme offers optimal adaptability to foundation deformation and the best economic efficiency.Its seepage control effectiveness and construction efficiency are significantly superior to those of traditional schemes,and its maintenance convenience meets operational requirements.Consequently,this composite scheme is recommended as the representative reservoir basin anti-seepage solution for the pre-feasibility study stage,aiming to provide key technical references for related anti-seepage designs of pumped storage power stations in karst areas.关键词
