The comparison and selection of seepage control scheme of reservoir engineering is an important technical link of seepage control treatment of reservoir reinforcement engineering,which has great engineering significance for the scientific design of seepage control treatment measures.Therefore,the practice case of the reinforcement of Longbakou Reservoir Project in Gonghe Village,Xitou Town,Renhuai City is studied.The project situation is understood.The leakage characteristics of Longbakou Reservoir Project are studied.The comparison of anti-seepage scheme of Longbakou Reservoir Project is completed by analyzing the characteristics of horizontal and vertical anti-seepage scheme.At the same time,the anti-seepage curtain grouting line layout and the anti-seepage curtain grouting line comparison selection are implemented.Finally,the anti-seepage scheme of Longbakou Reservoir Project is determined.It can provide a reference for the comparison of the reinforcement and seepage prevention schemes of similar reservoir projects.
