文章对一期整治工程布置、整治前后来水来沙及河道地形变化进行了分析,并利用二维水沙数值模拟技术,对富锦—绥东河段修复工程进行多方案比选,提出了合理的整治原则及工程措施,修复工程实施后富锦—绥东河段航道尺度可达到Ⅲ级航道标准.%In this paper, the general layout of the first phase of channel regulation project, the variation of channel topography, and the incoming water and sediment before and after regulation project were analyzed. Based on a two-dimensional flow sediment mathematical model, various schemes of the restoration project of Fujin-Suidong reach were compared.Then the channel regulation principle and engineering measures were presented.After the implementation of channel regulation project,the channel dimension of Fujin-Suidong reach is possible to get the Ⅲ grade channel standard.
