黄河下游河道形态塑造技术研究

Research on Channel Morphology Shape Technology in the Lower Reaches of the Yellow River

针对黄河下游河道形态目前存在的二级悬河等问题,依靠泥沙利用和泥沙固结新技术,提出了在河南段按3条基本平行的过水通道进行设计、在山东段按复式断面设计单一过水通道的河道形态塑造方案:采用"取沙塑造河道→泥沙利用和泥沙固结→修筑控导工程→束水塑造河道"新方法,可逐步消除二级悬河的不利河势,同时为黄河下游的淤积泥沙提供资源化利用的新途径。

In the lower reaches of Yellow River channel form the existing secondary suspension,rely on the river sediment use and sediment,and put forward the new technology consolidation in Henan according to three basic principles for parallel water channel design,in Shandong province by double entry section design for a single water of river channel form shape scheme.The results show that： the scheme adopts the new method of ＂take sand to remold river course and sediment usage and sediment consolidation and built constraint works and bound water to remold river cours＂,at the same time,it provides the recycle of new ways for the sediment deposition in the lower Yellow River.
