摘　　要：预应力钢筒混凝土管道作为一种新型输水管材在水利行业应用十分广泛,然而对于其输水能力的水力学计算尤其是沿程水头损失计算,由于设计者选取的计算公式不同或者参数的不同导致了结果的不同或分歧。文中对几种常用计算公式方法及适用条件,进行简要分析论述,研究成果可供类似工程参考。As a new type of water delivery pipe,prestressed concrete cylinder pipe has been widely applied to water conservancy construction. But for the calculation of water carrying capacity,especially for the calculation of frictional head loss,there are different results due to the different calculation formulas or different parameters that the designers selected. This paper briefly analyzed some common calculation formulas and the suitable conditions,which is useful for similar project.
