| 摘 要： | 针对３台机组合用１条有压尾水隧洞的矩形阻抗式尾水调压室底部流道的体型进行了优化试验研究。研究了３种典型的底部流道体型的水头损失，以及机组负荷变化情况下不同的底部流道体型的水头损失与分流比的关系。结果表明，尾水调压室阻抗隔板下设曲线形分岔方案的流态较好，与常规无分岔的方案相比，减少水头损失的５０％，可显著提高发电效益。

| Abstract: | A model for optimization of
the bottom shape of the rectangular orifice surge tank in the tail tunnel used by three
units is studied in this paper.Measured are the head losses for three types of bottom
shape and the changes of head loss under different loads.The results demonstrate that the
curve bifurcation model is the best and its head loss is 50% less than that of the
non-bifurcation model.The bottom shape recommended can increase the efficiency of power
generation significantly. |

| Keywords: | surge tank optimization model head loss discharge rate bifurcation |
