Aiming at the safety problem of seepage flow change caused by geomembrane defect in the impervious res-ervoir of the full reservoir basin of pumped storage power station,taking the geomembrane impervious engineering of res-ervoir bottom of a pumped storage power station in Shaanxi Province for an example,single factor influence analysis and multi-factor influence analysis method were used to analyze the seepage defects of the full reservoir basin impervious res-ervoir of pumped storage power station.The results show that the height of head,the size of defects and the number of defects all have positive effects on the seepage flow of the reservoir,but the correlation between the location of defects and the seepage flow of the reservoir is not obvious.The size of defects is the main factor affecting the seepage discharge of pumped storage reservoir,the second is the height of head,and the third is the number of defects.
