| 中文摘要: |
| 水跃消能是水利工程中经常用到的消能形式,国内外许多学者对水跃进行了大量的研究。在工程实践中发现,c型折坡水跃的水力特征值与规范方法计算得到的值有较大差异。文章针对c型折坡水跃特性进行了试验研究,并结合量纲分析和数值分析方法,得出以斜坡段坡角θ为参数的c型折坡水跃跃后水深、水跃长度的计算公式,并利用水槽试验数据和实际工程水工模型试验对公式进行了验证。结果表明:所得公式的计算误差不超过±12%,可供工程设计计算参考。 |

| Hydraulic jump energy dissipation is a form of energy dissipation frequently used in hydraulic engineering. Many scholars at home and abroad did a lot of research on hydraulic jump. In engineering practice people found that hydraulic characteristic values of c-type fold slope hydraulic jump and the standard method for calculating the value has a bigger difference. Aiming at the characteristics of hydraulic jump with c-type fold slope the experiment was carried out, and combined with the dimensional analysis and numerical analysis method, obtained the calculation formula for the water depth after c-type fold hydraulic jump and hydraulic jump length under the slope angle as the parameter, and using flume test data and practical engineering hydraulic model test was verified. The results showed that the calculation error of the formula less than ±12%, therefore. It can provided some reference for engineering design. |
