摘要
本文根据理论分析建立了恒定急变流能量方程,进而导出了陡坡控制断面水深的表达式。计算结果表明,计算值与实测值符合较好。为推求陡坡水面线,引入了边界层排挤厚度,概念明确,方法简便。算例表明,本文算法与实测值符合较好。
In this paper, the energy equation of rapidly varying steady flow is established by theoretical analysis, and the expression of water depth of control section on steep channel is deduced, the calculation results are in good agreement with actual results. In order to calculate the water surface line along steep channel, the extruding thickness of boudary layer is introduced, the concept is clear and the calculation method is simple.
