摘　　要：我国北方渠灌区多以多泥沙河流为水源,管道淤堵问题是影响管道输水灌溉技术在渠灌区推广应用的制约因素之一。而解决浑水管道泥沙淤堵问题的关键在于确定其临界不淤流速及与之配套的工程技术措施。结合国家“863”研究课题部分成果,根据北方浑水渠灌区特点和运行实际,分析研究了浑水管道淤堵机理,提出了一整套行之有效的管道防淤堵技术措施,并结合工程进行了示范,取得了良好的效果。Multi-sediment river was regarded as source of water in northern channel irrigation area. Which irrigation technique of water delivery in pipeline being extended and applied is restricted because of sediment depositing in pipeline. Solving sediment depositing in pipeline key of problem lied in determining non-depositing critical velocity of muddy water delivery in pipeline system and corresponding technical measures. The text was based on partial outcome of national '863' plan issues, analyzed and studied sedimentary mechanism of water delivery in pipeline, generalized valid technical measures and extended it in the field.
