针对玻璃钢管沿程水头损失计算问题，根据水力学原理，采用公式对比的方法，论证了海曾2威廉公式的合理性，并修正了相关参数；同时以新疆小洼槽倒虹吸为例，利用不同公式计算水头损失值，然后与实测数据比较分析，发现管径小于2000 mm 玻璃钢管的水头损失计算宜采用海曾2威廉公式，沿程摩擦系数采用相应的修正值；管径大于2000 mm 宜选用齐恩公式和达西公式的组合。

As for the calculat ion of friction head loss in the FRP pipe, based on the hydraulics principle, several formulas were compared and the rationalit y of H azen-Williams formula w as demonstrated, and the relevant parameters w ere modified. T he study adopted different formulas to calculate the water head loss in the case of small-trough inverted siphon in Xinjiang. The re-sults of the com parison betw een the calculated and observed head loss suggested that: ( 1) H azen-Williams formula can be used in the friction head loss calculation in the FRP pipe w ith diameter less than 2 000 mm, and the frictional coefficient needs to be modified; and ( 2) the combinat ion of JiEn formula and Darcy formula can be used in the friction head loss calculat ion in the FRP pipe w ith diameter larger than 2 000 mm.
