摘　　要：通过管道输水试验系统,对浑水管道输水系统水沙运动规律进行了深入细致的实验研究,并以实验为基础,运用泥沙运动力学和管道水力学原理,对浑水管道阻力损失规律进行了探讨,得出了浑水管道阻力损失计算经验公式,为今后管道输水灌溉技术在渠灌区的推广应用和有关水力计算提供了科学依据。Sediment in hydraulic flow within pipeline has some influence to the glutinosity and the turbulence of water current, also the energy conversion and loss. Therefore, water head loss is different between muddy and clear water. The prior planning and design of pipeline networks in irrigation area irrigated with muddy water had to use the formula of clear water head loss for short of the data of muddy water head loss and theory reference. However, it is lack of reliability to do like that. The motion regularity of sediment and water was studied particularity by using muddy water delivery pipeline system, thereby discussed the law of muddy water head loss. The empirical formula of muddy water head loss within pipeline was approached. All these were very useful to generalize further the technique of water delivery in pipeline system in channel irrigation area and to offer scientifical reference for related hydraulic calculation.
