摘　　要：为验证福建省洋口水库水工溢洪道设计参数指标及布置的合理性,对该水库的泄流能力、水流流态、消流防冲、冲坑形态、河道冲刷等方面进行模型试验,并对挑流鼻坎体型参数进行优化,增加差动鼻坎,从而减轻下游河床冲刷。结果表明:溢洪道泄流能力达到设计要求,溢洪道流态稳定,鼻坎优化方案明显改善了消能效果,研究成果对类似工程结构设计优化有一定借鉴意义。In order to verify the design of the spillway parameters and layout scheme in Yangkou Reservoir,Fujian Province,issues such as flood discharge capacity,flip energy dissipation effect,shape and range of the scour pit,river channel erosion were studied through hydraulic model test,and an optimization plan for the flip bucket was proposed.The results showed that the discharge capacity of the spillway can meet the design requirements,and the flow state of the spillway was stable.The optimized scheme of the flip bucket significantly improved the energy dissipation effect.The research results have some reference significance to the optimization of structural design of similar projects.
