摘　　要：为确定黄河下游引黄灌区浑水管道输水沿程阻力系数,以黄河泥沙为沙样,在室内用U-PVC管道进行了110、125mm管径条件下不同含沙量、不同流量的浑水管道阻力实验。结果表明,引黄管道水流属于过度粗糙区,管道输水沿程阻力及沿程阻力系数与管径、流量、含沙量、雷诺数等因素有关。得到的浑水管道输水沿程阻力系数经验公式的计算精度较高。In order to determine the frictional resistance coefficient in the muddy water pipeline conveyance of the Lower Yellow River irrigation area,the experiments with U-PVC pipes ofФ110mm andФ125mm were conducted under different concentrations and different flow rates.The results showed that the flow belonged to excessive rough area,and the pipeline frictional resistance and the frictional resistance coefficient both were relevant to pipe diameter,flow,sediment concentration,Reynolds number,etc.The experience formula of the calculation for on-way resistance coefficient in the muddy water pipeline had higher calculation accuracy.
