摘　　要：分析了黄河银川段贺兰滩群滩槽、浅滩变化与碍航特性。针对研究河段存在的河宽水散、槽窄水浅、弯曲半径小、主流频繁摆动等问题,确定了"因势利导,枯水整治,固滩稳槽,堵支强干"航道整治原则。建立了该河段航道整治物理模型,对整治工程方案进行了深入的试验研究。结果表明:该河段应低水整治,整治水位不宜过高。以固滩为主要目的兼具整治功能的整治建筑物,其整治水位采用设计水位以上0.5 m。推荐方案试验表明,工程后枯水期水流归槽,航道尺度达到建设标准,航道通航条件也有明显改善。The variation of beaches, shoals and channel and the nature of navigation obstruction were brieflyanalyzed in this paper. For the problems of wide river and scattering water, narrow channel and shallow waters,small bending radius and continually swinging main current existing in the Helan beach groups of Yinchuan sectionin the Yellow River, the principles of waterway regulation about ＂to make the best use of the situation, to regulateduring low water, to firm the beach and stabilize the channel, to block up the branch and strengthen trunk＂ were de-termined. The physical model of the reach was established to study waterway regulation schemes of the Helan beachgroups. The research result shows that the channel should be regulated during low water, and the regulation waterlevel should not be too high. It should be 0.5 m above design water level. After the recommendation scheme beingcompleted, the water will return to channel during dry season, and the channel dimension will be up to constructionstandard. The navigation condition of the reach will be improved obviously.
