摘要
本文根据黄河口实测水文泥沙资料,分析拦门沙形成的原因,阐明了泥沙在滞流点附近的淤积过程。 由于黄河流域来沙量大,单靠疏浚方法难以取得满意的治理效果。根据目前渲泄洪水泥沙和排凌,稳定流路的要求,提出了借助自然力量,降低拦门沙高程的治理途径。
This paper, based on observed field data of hydrology and sediment, anlyses the reason of the formation of sand bar and, presents the process of sedimentation near the stagnation point.Because of the great quantity of sediment from the basin in the Yellow River, the speed of the seaward extension is fast at the coastline of the river mouth. The regulation of the bar only by dredging can not be satisfied. According to the need to drain flood and flush away sediments, the way of regulation that degrades the elevation of the bar with the aid of natural forces was developed.
