Research on Energy Dissipation Type of Overflow Dam in a Reservoir

ZHANG Ge,LIU Ya-kun,SUN Hong-liang,ZHOU Le(College of Water Conservancy Engineering,Dalian University of Technology,Dalian,Liaoning 116024,China)  
The model experiment is usually used to choose the type of energy dissipation in release structures.Here,several kinds of energy dissipators such as irregular broad tail pier,differential flip bucket,and the combination of the irregular broad tail pier and differential flip bucke are used to solve the scour problems caused by the flood discharge of a reservoir.By comparing the scour characteristic values of all model tests,the energy dissipation scheme combined with the irregular broad tail pier and differential flip bucket is recommended.The test results show that the recommended combination energy dissipation scheme is better than the primary scheme with flat gate pier in the respect of project safety,which could eliminate the energy of flood effectively,thus reducing the downstream scour and protecting the project to operate safely.
