摘　　要：以尊村灌区一干改造渠段为例,研究渠道泥沙输移特性及冲淤变化规律。通过沿程悬移质、床沙质取样和实测流速,分析渠道淤积成因。结果表明,淤积最严重情况发生在渠首,停水期泥沙淤积是造成渠道淤积的重要因素,给出了各输水工况下应满足的挟沙流速,为今后渠道减淤,灌区高效运行提供了依据。Taking a reconstruction canal section in Zuncun Irrigation District as the research object, this paper studied the sediment transport characteristics and scouring and silting change law of the canal. The causes of channel siltation were analyzed by sampling suspended matter, bed sand and measured velocity. The results show that the most serious siltation occurs at the head of the canal, and the siltation during the water shut-down period is an important factor causing the siltation of the canal. The flow rate of sediment carrying under each water conveyance condition is given, which provides the basis for the reduction of siltation and the efficient operation of the irrigation area in the future.
