摘　　要：应用数值模拟方法,对戴家洲洲头不同地形下的水流特性、洲头分流面等进行了认识性计算分析。计算分析结果表明,该河段航道整治在选汊以及工程布置等方面都应以数值模拟认识性计算结论为基础。通过大量方案计算,数值模拟得出了该河段航道整治总体工程方案,整体方案工程经系列水文年过程校核,可以满足该河段远期规划航道尺度要求。In order to improve the navigation state and to meet the need of the dimensions of the channel of longterm program, the navigation regulation engineering should be carried out in the section of Daijiazhou. The flow state and distributary surface in beach - head under various geomorphie conditions are numerical simulated in this paper. The calculating results illustrate that the selection of the location of branch and the layout of project, etc should be on the basis of the results of the numerical simulation. According to a number of calculating results of numerical examples, the overall plan of navigation regulation in this section is obtained, which is verified to meet the need of the dimensions of the channel of long - term program by real hydrological information with a serious of years.
