摘　　要：某些中小型水库工程由于地形或地质条件的限制,既不适合采取挑流式消能,又不宜采用底流式消能,在这种情况下,采取多级连续消力池消能也许是不错的选择。本文结合湖北省丹江口市金岗水库溢洪道的除险加固设计,系统地介绍了多级连续消力池的布置方案和水力计算方法。结果表明多级消力池消能方案,提高了工程消能率,降低了水流流速,提高了河床抗冲刷能力,并且多级消力池没有统一的形式、高度、尺寸等,可因地制宜根据各种工程特点来满足各自的经济技术要求。It is not appropriate to take ski-jump energy dissipation either to take bottom-flow energy dissipation for some small and medium sized reservoirs because of the terrain or geological conditions.In this case,the multi-stage continuous stilling basins may be a good choice for energy dissipation.Taking the reinforcement design for the spillway of Jingang Reservoir in Danjiangkou City of Hubei Province as an example,the layout program and hydraulic calculation method of the multi-stage continuous stilling basins are introduced here systematically.The results show that the multi-stage stilling basins can increase the energy dissipation rate,reduce the flow velocity and improve the anti-scour ability of the river bed.Since there is no unified form,height and size etc.,the multi-stage stilling basins can be designed and installed to satisfy each economic and technical requirement in the light of local conditions.
