摘要
从理论上讨论了用于复式断面渠道的传统的断面剖分计算法的计算误差 ,并提出了一种新的断面等速剖分法。该方法要求各剖分断面流速相等 ,从而消除了传统的断面剖分法因未考虑各剖分断面之间由于流速梯度而引起的切应力所产生的误差。
This paper discusses the calculation error of traditional dividing section method in complex section channel by theoretical analysis,and produces a new dividing section method which the velocity of dividing section is equal. This new method requires that veloci ty of dividing section is equal,and the traditional error is not in existence,wh ich is produced by stress that is produced by velocity gradient between the dividin g section and is not considered in traditional dividing section method.
