| 摘 要： | 以龙开口水电站冲沙底孔泄槽段为例,针对常规掺气设施不能确保掺气效果问题,基于原设计方案提出了2个优化方案,并通过水工模型进行了试验和比较分析,确定了较合理的掺气设施。结果表明,有压出口底部采用突跌掺气并加设挑坎,泄槽段采用坎槽结合式的掺气形式,掺气减蚀效果较好。

| Abstract: | The conventional aerating facilities can not ensure the aeration effect.Taking chute section of sand flush bottom outlet of Longkaikou Hydropower Station for an example,this paper proposes two optimized programs based on the original design scheme.The reasonable aerating facilities are determined with hydraulic model test.Results show that the program can produce a good cavitation reduction effect,which adopts the combination of sudden bottom drop for aeration and flip bucket in outlet of pressured spillway... |
