摘　　要：本文根据天然实测资料和河工模型试验成呆,对底沙输移特征与河床形态关系、航道整治工程对推移质输沙带平面形态的影响进行了初步分析,在此基础上提出了沙卵石河床边过渡段和汊流浅滩航槽定线、通航汊道选择以及整治建筑物布置原则。Based oa the field survey data aud research findings of river modei tests, this paper makes analysis on the relationship between characteristies of bedload movement and channel pattern as weil as the effect of waterway regulation eng ineering on the transport of bedload moving strip.On the basis of analysis, the principle of channel alignment for transition zone with sand - gravel bed, and the selection of bifurcated channel as well as the distribution of regulating structures are obtained in this paper.
