摘要
根据大源渡枢纽施工导流模型试验结果，着重分析了一期施工期间利用束窄后河道泄流及通航的水流条件。通过分析表明，束窄后河道具有明显的急流险滩特点，坝址流量大于5000m^3／s时，船舶航行困难。针对施工期通航水流条件，提出最佳航线设计和改善施工期通航条件的一些措施。
Based on the experimental result of construction river diversion model of Dayuandu, this paper studies the flow condition for navigation and drainage in first construction period. A analysisshows that there is remarkable character of rapids in narrowed river, it is difficult to navigatewhen discharge exceed 5 000 m^3/s. Furthermore, optimum design of navigation channel andsome methods of improving channel condition are provided.
