【摘要】 结合糯扎渡水利枢纽溢洪道掺气减蚀模型试验研究,根据试验资料,利用回归分析,拟合出关系曲线,建立了坎高与水深、流速、溢洪道底坡、挑坎挑角关系的经验公式,并通过已建成的工程实例来验证公式的实用性.该公式对掺气坎槽选型提供了依据,可供设计与模型试验阶段参考.更多还原

【Abstract】 This paper is based on the model experiment of Nuozhadu hydraulic complexes. We analysed the data of the experiment and used regress analysis to get the relation curve,then we set up a experiential equation,which indicates the relation between ridge height and depth,velocity,grade of spillway,grade of ridge. Furthermore. We validate the equation by some actual engineering samples. The equation offer some references in choosing fit shape of the spillway chute aerator in the course of design and experiment.更多还原
