| 摘 要： | 根据明渠均匀流理论，推求了抛物线形渠道正常水深与流量的关系和水力最优断面的计算公式，得出了水力最优断面水深与抛物线参数的关系为ah0=0.946732。与其它渠道比较结果表明，抛物线形渠道是仅次于U形渠道的又一水力最优断面。

| Abstract: | The formula of depth in open chanel uniform flow and runoff and the calculating method of optimal hydraulic cross section have been deduced, according to the theory of open chanel uniform flow. Also,the equation of the depth of the optimal hydraulic cross section and parabola parameter are derived,which is ah 0=0.946 732. The conclusion that the cross section of parabola canal is the subaltern optimal hydraulic cross section compared with the U-shape canal can be drawn. |
