摘　　要：调控泥沙沉积在沉沙池的合理位置,有效降低清淤难度与成本,是保障引黄工程输水能力与经济高效运行急需解决的关键问题。以引黄济青工程为研究对象,基于MIKE21模型建立引黄济青渠首输水渠道与沉沙池的二维水沙数值模型,模拟多种典型流量下泥沙的输移与动态变化过程,提出3种泥沙沉积调控方案,模拟分析各种调控方案的阻沙效果。结果表明:二维水沙数值模型能较好地模拟调控前后沉沙池的水沙输移状况;调控方案阻沙效果明显,淤积功能区的沉积量可增加10%,并可缩短沉沙长度、降低清淤成本。Regulating the reasonable position of sediment in the sedimentation basin and effectively reducing the difficulty and cost of dred⁃ging are the key issues to be solved in the economic and efficient operation of the Yellow River Diversion Project.Based on the Mike21 mod⁃el,a two⁃dimensional water and sediment model was established to simulate the process of sediment transport and dynamic change under vari⁃ous typical flows.Three sediment deposition control schemes were proposed to simulate and analyze the effect of various control schemes.The results show that the two⁃dimensional numerical model of water and sediment can better simulate the change of water and sediment transport in the sediment basin before and after the regulation.The regulation scheme has obvious effect on sediment control.The sedimentation volume in the upstream of the designated control section is increased by 10%.It can shorten the length of sedimentation deposition and reduce the dred⁃ging cost.
