| 摘 要： | 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。

| Abstract: | Through the hydraulic experiments of the over-flow earth-rock dam,the data of experiments were analyzed.The results showed that when spillway has many aeration ridges,the distributing of dynamic water pressure is abnormity.It was found that the data measured by the hydraulic experiments made a great difference with the data counted,and the different position with the different change.At last,from the contrast of two projects,the advice on fixing parameter had been given. |
