摘　　要：潘口水电站溢洪道具有流量大、水头高,挑流水舌与河道夹角相对较大的特点。溢洪道设计充分利用了有利的地形地质条件,采用直线等宽矩形泄槽,保证了水流流态的相对均匀稳定。结合水工模型试验成果,对潘口电站岸边溢洪道各部位体型进行了优化,使溢洪道在泄流能力、各部位水流流态以及挑流消能效果方面都有了很大的改善,能够更好地满足溢洪道运行安全的要求。The spillway of Pankou Hydropower Station is characterized by large discharge, high water head, large angle be- tween water jet and river channel. The favorable geological conditions are fully utilized in the spillway design. The linear rectan- gular discharge trough is adopted to make sure the flow pattern is relatively stable and even. Combining with the experimental re- sults of hydraulic model, the shape of every part of the spillway is optimized. So, the discharge capacity, flow pattern and trajec- tory energy dissipation are significantly improved to meet the demand of safe operation of the spillway.
