摘　　要：针对某工程拦河坝泄水孔口较多且下游河谷狭窄陡峭的问题,采用“分区消能+分散入水”的消能思路,将表孔调整为斜切坎,底孔调整为燕尾坎,同时结合后期运行方式,得到了较优的各挑坎体型,实现了上下游水流的良好衔接,可以为类似的工程问题提供借鉴。Be aimed of the problems that the quantities of water outlet of water dam are more and downstream river valley is narrow and precipitous in a project,in this paper,the author,took the thought energy dissipation by dividing reach adding releasing water through dispersing,turned crest spillway to oblique cut,turned bottom outlet to dovetail ridge,meanwhile combining operation pattern in later stage,and obtained each better bucket type,also realized good cohesion both upstream flow and downstream flow.The results can be provided for reference in solving similar project problems.
