摘　　要：通过对长江中游蕲春水道河床演变及碍航特性的分析,利用河工模型试验对6.0 m水深航道整治工程方案的整治效果进行研究,确定了蕲春水道整治工程方案,由李家洲边滩1道潜坝、3道护滩带、高滩守护和左岸护岸加固工程组成。研究结果表明,本工程的影响只局限于工程区域及附近,对总体河势、防洪、堤防等外部环境影响较小,左岸护岸加固工程进一步增强了左岸岸线的稳定。研究为复杂外部环境下航道整治工程方案设计积累了一定经验。Based on the analysis of riverbed evolution and navigation-obstructing characteristics of Qichun waterway in the middle reaches of the Yangtze River,this paper studies the effect of the project scheme for regulating the waterway with a depth of 6.0 m by river model test and determines the regulation project scheme of Qichun waterway.The project scheme consists of a submerged dam project on the Lijiazhou beach,a project of three shoal protection belts,a high shoal protection project,and a revetment reinforcement project on the left bank.The research results show that this project scheme only affects the project area and its vicinity and has a slight impact on the overall river regime,flood control,embankments,and other external environments.The revetment reinforcement project on the left bank further enhances the stability of the shoreline on the left bank.The research provides some experience in designing channel regulation project schemes under complex external environments.
