Test and research of overflow weir flaring-tail pier energy dissipation for Liujiadong Hydropower Station

LI Xia(Guangxi Water Science Research Institute,Nanning 530023,China)  
The problems of Liujiadong Hydropower station are analyzed by hydraulic model test,including discharge from overflow dam concentrating too much without sufficient energy dissipation,having scouring pit downstream of dam due to insufficient water depth.The author suggests to dissipating energy by use of flaring-tail pier and conducted corresponding test.The results of test demonstrate that application of flaring-tail pier in ski-jump overflow dam will be able to improve the skj-jump energy dissipating effect,alleviate scouring at downstream river bed and ensure safety of overflow dam.
