Abstract: This article deals with the calculation of flow coefficient which is in a water-transporting system of the short pressure pipeline of a chamberlock. On the basis of the linear assumption and the computation looking up tables, the assumption of secondary curve is used to make the theoretical value of flow coefficient near an actual condition all the more. And a series of calculative formulas of water force is induded, and the theoretical analysis is provided for the design of the water-transporting system in a chamberlock.

Key words: flow coefficient, water force, characteristic curve

摘要： 本文对船闸短廊道输水系统的流量系数计算进行了一些探讨,在原有的直线假定和查表计算的基础上,进行了二次曲线假定,使其流量系数的取值与实际情况更加接近。并且,由此导出了一系列水力计算的公式,为船闸短廊道输水系统的水力计算,提供了一个更为完善的设计依据。
