摘　　要：结合黄金坪水电站枢纽整体设计要求,考虑其地形地质条件的限制,对其消能形式和体形进行了优化研究,提出了新型掺气型阶梯消能方式。通过试验对原设计方案、比选方案及推荐方案进行了对比研究,结果表明,推荐方案不仅消能更加充分,下游冲刷较轻,整个枢纽泄洪运行调度更加方便灵活,而且可减少开挖和防护工程量,节省工程投资。Based on the overall design of Huangjinping Hydropower Station project and by considering the limitation of topographic and geologic conditions, the form and shape optimization of energy dissipater of discharge structures are studied. A new pre-aerator stepped energy dissipator is finally proposed. Many experiments are carried out to compare the original designed scheme, alternative scheme and proposed scheme. The results show that the proposed scheme can not only make the energy dissipation more effective, the downstream erosion less and the flood control scheduling more convenient and flexible, but also can reduce the amount of excavation and protection engineering and save project investment.
