The research on hydraulic model test of overfall dam for Shanggou key water control project

CHANG Yun-hua,et al.(Faculty of Water Conservancy & EnvironmentEngineering,Changchun Institute of Technology,Changchun 130012,China)  
According to the special topographic and geological condition of the damsite's lower reaches,by establishing the hudraulic phusical model of Shanggou Overfall Dam in propontion as one to sixty,we make observations of the dam's flow form under different conditions at operation,a thorough research on the problems of the scour which will be caused by the lower riverbed and mountain massif,and the landslide which will be brought out by the atomagation produced likely and,moreover,the operation control ways of sluice gate's discharge dispatch are given.At the same time we make a rather thorough test research on the problems of the dam's discharge capacity,scouring pit depth,deflection distance,influence of hydropower station's tail water and cavitation and cavitation erosion.Especially we conduct to optimize the designs for the form of the dam's pier,deflector angle and the type of build for the tail tailrace guide end wall of the power station.
