摘要
弯曲溢洪道是由于地形地貌及原河道走势等因素而出现的布置型式,阐述其不对称水流特征及对下游消能的影响,通过优化工程措施,改善弯曲溢洪道的水流特征,从而改善下游消能效果,能够为实际工程设计提供帮助。
The layout of bend spillway is caused by the factors of topography and the original river trend. The article sets forth its asymmetric flow characteristics and its influence on the energy dissipation of the lower reaches. The optimization of engineering measures can improve the flow characteristics of bend spillway so as to promote the energy dissipation effect of the lower reaches and able to provide the help for the design of practical projects.
