2) concave aeration ramp
凹形掺气坎
1.
Based on the 1∶60 scale model of Xiaowan tunnel spillway, physical model text is carried out for the optimum design of aeration facilities, the new concept of "equivalent height of ramp" is brought forward and the layout of concave aeration ramp is suggested for aerator under mild gradient.
从物理机制上看,平面凹型掺气坎因空腔内水气交界面积大,对提高空腔内的总通气量、改善掺气条件有利;另外,相对于其他异型掺气坎而言,凹形掺气坎在两侧边墙处空腔更为完整一些,这对提高边壁角隅区域水流的掺气能力,增进边墙的抗空蚀效果也有一定的助益。
3) three-dimensional aeriferous

利用已有的试验资料分析了泄槽设置掺气挑坎后对水面线产生的扰动影响。
2.
The results showed that when spillway has many aeration ridges,the distributing of dynamic water pressure is abnormity.
通过对已有溢流混凝土面板堆石坝模型试验成果的分析,发现当泄槽设置多道掺气挑坎时,由于掺气挑坎对水流的扰动影响,使得泄槽底板上的动水压强分布极不规则,作用于泄槽底板上动水压力的模型试验实测值与计算值相差较大,并随底板在泄槽中所处的位置而变化;根据模型试验实测值与计算值的对比,提出了计算底板动水压力时的修正建议。
6) bucket aerator
