【摘要】 有关高速水流泄水建筑物掺气设施体型优化方面的研究还没有成熟的理论方法,此研究拟通过模型试验的方法取得掺气减蚀设施的体型优化成果。结合大渡河猴子岩水电站洞式溢洪道的大比尺水工模型试验,根据规范,采取3道掺气设施,并对掺气设施挑坎坡度、高度和跌槽深度对比选优,对高水头溢洪道掺气减蚀设施进行优化研究。试验表明,通过改善掺气设施型式,可以有效减免反弧段空化和气蚀。成果可供设计高水头、大流量洞式溢洪道掺气设施体型参考。更多还原

【Abstract】 According to the large-scale hydraulic model experiment for the spillway of Houziyan Hydropower Station,the optimization design and study are made for the cavitation-control aerator of a high-head spillway,including the comparison and optimization for the bucket height and drop chute depth.The experiment results show that improving the aerator could decrease or eliminate the cavitation and erosion in deflector bucket.The study could provide references for the design of the spillway with high head and large discharge.更多还原
