| 摘 要： | 本文根据边界层理论计算壁面阻力的方法分析了明渠测流槽流量的计算问题。并把这种方法应用于Ｕ形（圆底形）喉道测流槽和Ｕ形渠道直壁槽式量水堰。模型试验及原型观测结果证明，理论计算和实际观测吻合。因此应用边界层理论来计算测流槽的流量，不仅从理论上研究了测流槽的量水问题，简化了繁琐的试验率定，而且具有重要的实用价值。

| Abstract: | The question upon the discharge calculation of flow-measuring flume is analysised according to the calculating method of surface drag from the boundary layer theory, and the method is used in the discharge calculation of flow-measuring flume of U-shaped channel with the straight walls and the throat.The model experiment and the prototype observation proved the results of theoretical calculation and practical measurment. Therefore,the boundary layer theory in surface dray calculation of flowmeasuring flume is not only discussed in the paper but also in practical activities. |
