摘要
为了能够快速准确计算明槽水面线,有必要针对曲底明槽渥奇段水面线的计算方法进行研究。本文根据明渠非恒定流的基本微分方程,导出计算明槽水面线的基本方程,并进行了试验验证,计算结果能很好的符合实测水面线,计算结果误差小于1.6%。研究结果对曲底水面线计算有较大帮助。
For rapid and accurate computing the water surface profile, it is necessary for study of the open canal with arch. This paper bases on the basic differential equation for open canal unsteady flow, infers the basic equation to compute the water surface profile for open canal with arch bed. And it was verified by experiment, the result shows this method can compute the water surface profile accurately,the outcome error is little than 1.6 %. The outcome is more help to be used the compute the open canal with arch bed.
