摘　　要：白鹤滩水电站泄量大、水头高,泄洪消能设施布置难度较大;针对白鹤滩水电站坝身泄洪的特点,对泄洪消能孔口布置方案进行了比较研究。坝身布置6个表孔、7个深孔,提出了坝身表深孔优化布置方案,使水舌横向扩散并纵向拉开,以有效地降低水垫塘冲击压强和脉动压强。1∶50水工整体模型验证试验表明,推荐方案安全可靠,合理可行。Baihetan Hydropower Station has large discharge and high water head,so it is difficult to arrange flood discharge and energy dissipation facilities.According to the flood discharge characteristics of dam body of Baihetan Hydropower Station,this paper makes a comparative study on the layout schemes of flood discharge and energy dissipation orifices.6 surface holes and 7 deep holes are arranged in the dam body.An optimum layout scheme of the deep holes on the dam body surface is put forward,which enables the water tongue to spread transversely and pull apart longitudinally,so as to effectively reduce the impact pressure and pulsating pressure of the cushion pond.The validation test of 1:50 hydraulic integrated model shows that the recommended scheme is safe,reliable and reasonable.
