【摘要】：黄河下游宽滩河段具有重要的滞洪沉沙作用,为了维护黄河下游河槽均衡稳定,治理"二级悬河",合理利用泥沙资源,开展了黄河下游宽滩河段泥沙均衡配置研究。提出了黄河下游宽滩河段泥沙均衡配置方法,通过黄河下游宽滩河段泥沙配置层次分析,确定泥沙配置目标和评价指标,分析了黄河下游宽滩河段泥沙均衡配置的配置方式、配置单元和配置能力,并建立了黄河下游宽滩河段泥沙均衡配置数学模型。
[Abstract]:The Guantan reach of the lower reaches of the Yellow River plays an important role in flood detention and sediment sedimentation. In order to maintain the equilibrium and stability of the lower Yellow River channel, to control the "secondary suspended river" and to make rational use of sediment resources, the study on the sediment equilibrium allocation in the lower reaches of the Yellow River has been carried out. This paper puts forward a method of sediment balance allocation in the lower reaches of the Yellow River. Through the hierarchical analysis of sediment allocation in the lower reaches of the Yellow River, the objective and evaluation index of sediment allocation are determined, and the allocation mode of sediment equilibrium in the section of the lower reaches of the Yellow River is analyzed. The mathematical model of sediment balance allocation in the lower reaches of the Yellow River is established.
