摘　　要：董箐水电站工程溢洪道泄槽宽度达50m,根据掺气减蚀原理,设计出了一种适应宽大泄槽的新型掺气坎体型。经数值计算分析,新型掺气坎掺气效果更明显、均匀,解决了宽大泄槽中部掺气的技术难题。该新型掺气坎结构简单、易于施工、效果明显,具有良好的推广应用价值。Dongqing Hydropower Station Project spillway chute width is up to 50m. A novel aerator shape suitable for large chute is designed according to aeration cavitations reducing principle. Novel aerator has more prominent and evener aeration effect according to numerical calculation analysis. Technical difficulty in aeration in large chute is solved. The novel aerator has advantages of simple structure,easy construction and prominent effect with excellent promotion application value.
