摘　　要：溢洪道陡槽段的外凸型阶梯跌坎是一种新型的消能工。溢洪道陡槽段设置了外凸型阶梯跌坎之后,可大大增加陡槽段泄流的消能率,减小陡槽段下游消力池尺寸和工程量。根据广东省4座水库溢洪道和拦河闸外凸型阶梯跌坎消能工的应用和原型观察,介绍溢洪道和拦河闸陡槽段的不连续外凸型阶梯消能工运行情况,供工程设计和运行参考。Outer bulging stepped drop sill is a new type energy dissipater in chute spillway.It can greatly increase the dissipation rate of chute discharge and reduce the dimension and quantities of downstream stilling basin.The operation status of discontinuous outer bulging stepped energy dissipaters of spillway and barrage chute are introduced based on the application and prototype observation of four (4) reservoirs in Guangdong to provide reference for other projects' design and operation.
