| 摘 要： | 分析了前人对平底渐扩式消力池共轭水深和自由水跃长度的研究成果；应用不同计算方法计算了平底渐扩式护坦末端消能坎的高度。结果表明：文献1]中计算消能坎高度的方法较为可靠，而采用文献7]中的计算方法所得消能坎的高度偏小。最后从原理上分析了采用文献7]的计算方法计算结果偏小的原因，建议平底渐扩式护坦末端消能坎高度的计算采用文献1]中的方法。

| Abstract: | The previous studies on the conjugation water depth and the length of free hydraulic jump for a gradually expanding stilling basin were analyzed. The height of obstacle at the end of a gradual expanding flat- bottom stilling basin was calculated by different calculation methods. The comparative analysis of calculation results shows that the method in the literature 1 ] is more reliable, and the height of obstacle calculated by the method in the literature 7 ] is too small. Finally, the paper analyzed the factor causing the calculation value of obstacle height being too small, and suggested the calculation method in literature 1 ] should be used. |

| Keywords: | gradual expanding flat - bottom stilling basin conjugation water depth height of obstacle |
