摘要
本文应用边界层理论和临界水深理论，讨论了明渠测流槽的设计方法和流量计算方法．并用三角形测流槽，Ｕ形渠道直壁槽式量水堰和梯形测流槽的试验资料和原型观测资料进行了对比分析，计算值和实测值一致．这种计算方法简化了试验率定程序，具有足够的测流精度，为测流槽的设计和流量计算的标准化提供了理论计算方法．
The method for hydraulic design is discussed according to the boundary layer theory and critical depth theory. The computational value are compared with the experimental data of triangular broad crest weir, U shape channel weir with straight walls and trapezoidal measuring flume. The results show that good agreement is attained.
