摘要
根据明渠均匀流理论,推求了立方抛物线形渠道正常水深与流量关系的计算公式及其水力最优断面所满足的条件.与其他形式断面渠道的比较结果表明,立方抛物线形断面渠道也是一种水力较优的输水渠道.
The formula of discharge varying with normal water depth in cubic parabola shape open channel uniform flow and the conditions satisfied by the optimal hydraulic cross-section in the cubic parabola shape channel were deduced according to the theory of open channel uniform flow. Compared with other types of open channel cross-section, the cubic parabola shape open channel is one of the open channels which convey water more efficiently.
