摘　　要：下凯富峡水电站坝址处河道狭窄、溢洪道泄洪落差和单宽流量较大、溢洪道出口位于坝脚附近,溢洪道泄洪安全是本工程的关键问题。通过水工模型试验研究,对溢洪道闸墩墩尾体型及鼻坎消能工体型进行了优化,改善了溢洪道泄槽流态,解决了溢洪道泄洪消能防冲的问题。The river reach at dam section of the Kafue Gorge Lower Hydropower Project is narrow, the discharge fall of the spillway is high, and the unit width discharge is large. The exit of the spillway is near the dam foot and the discharge safety of the spillway is a key issue for this project. Through hydraulic model test research, the shape of the spillway pier and the flip bucket energy dissipator are optimized which improves the flow pattern in the spillway chute and solves the problem of flood discharge and energy dissipation.
