| 摘 要： | 在深覆盖层河流上采用土石过水围堰度汛方案存在一定风险,但采用合理围堰体型和过流保护措施,能够实现围堰安全度汛。以猴子岩电站土石过水围堰体型为研究对象,通过模型试验,分别对单梯型围堰和面流消能型围堰进行了研究。试验结果表明,对于深覆盖层河流,围堰堰脚的防护尤为重要,采用面流消能型围堰过流效果优于单梯型围堰。

| Abstract: | Practice indicates that using the way of diversion through earth-rock overtopped cofferdams on overburden layer river is of certain risk.But with appropriate body shape and some protection measures,the cofferdams will be safe during the flood season.Based on the overtopped cofferdam of Houziyan Hydropower Station,the simple cofferdam and the surface energy dissipation cofferdam were studied through the hydraulic model test.The test results indicate that the hydraulic condition in the shape of the surface en... |
