明流管(渠)道非均匀流水面线的推算是一项繁琐费时的工作。国内外学者就此进行过大量的研究。为了进一步寻求简化计算的新途径,在前人研究的基础上,本文提出对矩形和圆形管(渠)道的水面线的等值线法以及备有辅助图表的分段累计法。
It is a tedious and time-consuming work to calculate the non-uniform flow line of the Ming-Dui (canal) channel. Domestic and foreign scholars have done a lot of research. In order to further search for a new way to simplify the calculation, based on the previous studies, this paper proposes the contour line method for the water surface of rectangular and circular tube (canal) channels and the subsection accumulation method with auxiliary charts.
