| 摘 要： | 乐昌峡水电站溢流坝具有泄流落差和单宽流量较大、下游河道狭窄等特点,溢流坝的消能问题较突出.通过水工模型试验研究,对溢流坝挑流消能工布置和体型进行比较,推荐溢流坝采用反弧段一体的扩散式梯形差动式挑流鼻坎的消能方案,妥善解决了溢流坝消能问题.

| Abstract: | The flood-releasing energy dissipation problem of the overflow dam at Lechangxia hydropower station is outstanding as it has large water head drop and the discharge per unit width of the dam is large,and moreover,the downstream is narrower.Based on hydraulic model test,the deflecting energy dissipator layout and configuration of the overflow dam are compared and hence energy dissipation problem of the overflow dam is solved properly in this paper by recommending diffusedal trapezoid differential flip bucket with overall ogee. |
