摘 要:
阳江抽水蓄能电站下库溢洪道具有泄流落差和单宽流量较大、陡槽段平面转弯等特点,溢洪道的急流冲击波和消能问题较突出。通过水力学模型试验研究,在弯曲陡槽段进口上游设置“底流消力池＋T型消力墩”的一级消力池、弯曲陡槽段内设置斜向高低坎和陡槽段内设置外凸式阶梯跌坎等辅助工程设施,改善了溢洪道泄流流态,妥善解决了溢洪道消能问题。[著者文摘]

Abstract:
With the characteristics of curved chute, relatively high flow drop and huge discharges in the downstream reservoir spillway of Yangjiang pumped storage plant, the project problems of torrent shock wave in curved chute and flood discharge energy dissipation are relatively outstanding. By hydro-model test, some auxiliary project means are used, such as stilling basin with T type pier in upstream of curved chute, high-low slope bank and bulge step dissipater in the chute. They improve the flow condition and properly solve the energy dissipation of the spillway.[著者文摘]
