水利水电技术（中英文）

利用水工模型,从波浪的角度对低坎分流墩用于低佛氏数水流消能的效果进行了试验研究。研究分析了水流的平均波高、波动能量、各波动要素随流程和随佛氏数的变化规律,以及波动沿频域的分布情况等等。结果表明,低坎分流墩用于低佛氏数水流消能效果良好,可有效地削减下游波浪,对下游岸坡稳定及通航有利。

By using of hydraulic structure model, some experiments have been done to research the energy-dissipation effect of diffluent piers with low ridge from the view of wave in the condition of low Froude current. This article analyses the average height of wave, the energy of wave, and their changeable rules with Froude, distance and frequency. The result of this research shows that diffluent piers with low ridge are effective to the energy dissipation. They can decrease the height of the wave and bring some advantages to the stability of the river bank and navigation.
