摘　　要：在水利枢纽布置中,多采用竖井式溢洪道,退水隧洞与导流输水隧洞相结合,减少地表土石方开挖扰动。本文介绍了竖井式溢洪道环形溢流堰的水力计算及漏斗段体型的设计计算,为水工设计提供参考依据,拓宽溢洪道设计思路。Shaft spillway is mostly adopted in key water control project layout. Water-break tunnel and diversion water conveyance tunnel are combined for reducing surface earth-stone excavation disturbance. In the paper, shaft spillway annular overflow weir hydraulic calculation and funnel section shape design calculation are introduced, a reference basis is provided for hydraulic design, and spillway design train of thought is broadened.
