Design of the Power Generation Water Diversion Cofferdams and Analysis of the Flood Passing Scheme for Guxue Hydropower Station

介绍了四川古学水电站引水式围堰的类型和结构布置,重点论述了在汛期被水流冲毁的围堰局部位置及冲毁的原因,对围堰转角处的流速进行了计算与分析,提出了防冲措施,可供类似工程参考。

Type and structural arrangement of the power generation water diversion cofferdams in Guxue Hydropower Sta -tion are introduced .Then, local damages occurred in the cofferdams during the flood season are illustrated and the pos-sible causes are discussed .Water flow velocity around the cofferdam corner is calculated .Some scouring protection measures are proposed correspondingly .It could be a useful reference for similar projects .
