尊村引黄灌区渠道水流挟沙力研究

Research on Water Flow Sediment-carrying Capacity of Zuncun Yellow River Diversion Irrigated Area Channel

[目的]掌握尊村引黄灌区渠道的冲淤情况。[方法]以尊村引黄灌区二干渠为研究对象,分析了渠道的挟沙力及影响因素。[结果]渠道夏灌时挟沙力要比春灌时大,不同灌溉期观测断面挟沙力的变化趋势基本一致;影响渠道挟沙能力的主要因素有流量、来沙含量等。[结论]该研究结果为解决渠道淤积问题提供了参考。

[Objective]The aim was to study the sediment situation of Zuncun Yellow River diversion irrigated area channel.[Method]The water flow sediment-carrying capacity and influence factors of Zuncun Yellow River diversion irrigated area channel were analyzed.[Result]The water flow sediment-carrying capacity of Zuncun Yellow River diversion irrigated area channel at summer irrigation stage was larger than that at spring irrigation stage,and the change trend of water flow sediment-carrying capacity of observation section at different irrigation stages was basically unanimous.The main factors affecting sediment-carrying capacity of Zuncun Yellow River diversion irrigated area channel were flow,sediment concentration,etc..[Conclusion]The result provides reference for alleviating channel siltation problem.
