Exploration of seepage control loophole and falling-pit risk removal plan in Nangou Reservoir dam

SHI Ning;Liaoning Yingkou Hydrology Bureau;  
Dam seepage failure risks mainly include dam loophole,falling-pit,etc. in the process of water conservancy project construction,especially dam body and its contact surface with dam foundation. There are extensive contact materials between dam body and dam foundation. Risk of dam foundation appears at the foundation level,thereby leading to higher risk on dam body. Dam patrol and inspection should be strengthened in order to prevent such conditions. The risky parts should be backfilled and treated,thereby ensuring safety of the reservoir dam during flood period.
