摘　　要：溢洪道是水库工程重要的结构物,其布置是否合理、泄流是否满足要求,直接关系到水库工程运行安全。依托某水库除险加固工程,根据设计方案制作出溢洪道水工物理模型,在消能防冲、设计洪水、校核洪水等工况下对溢流堰泄流能力展开模型试验;进而对溢流堰侧槽进口段、扩散段和消力池等结构体型与布置进行优化,可较好解决溢洪道运行中存在的水流流态紊乱、水面波动剧烈,空蚀破坏,消力池侧墙漫溢、河床冲刷等问题,为溢洪道结构的安全稳定提供可靠保证。The spillway is an important structure of the reservoir project.Whether its layout is reasonable and whether the discharge meets the requirements is directly related to the safe operation of the reservoir project.Based on the danger removal and reinforcement project of a reservoir,the hydraulic physical model of the spillway is made according to the design scheme,and the model test of the discharge capacity of the overflow weir is carried out under the conditions of energy dissipation and erosion prevention,design flood and check flood.Furthermore,the structural shape and layout of the inlet section,diffusion section and stilling basin of the side channel of the overflow weir are optimized,which can better solve the problems existing in the operation of the spillway,such as the disorder of the flow pattern,the violent fluctuation of the water surface,the cavitation damage,the overflow of the side wall of the stilling basin,and the erosion of the riverbed,so as to provide a reliable guarantee for the safety and stability of the spillway structure.
