摘　　要：三峡大坝—葛洲坝两坝间航道曲折多变,水流条件复杂。三峡电站调峰运行后引起航道水流条件的变化对通航将产生不良影响。根据船模实验最高安全限值的要求,通过船模通航实验,分析了不同船队在各关键航段汛期调峰时船队上下行航行的最大舵角、最大漂角、对岸航速及航行时间的变化;研究论证了汛期调峰时两坝间的通航条件,确保船舶安全通过此航段;提出了最佳航线、驾驭方式和航行难点。The waterway between the Three Gorges dam and the Gezhouba dam is zigzag and changeful and the flow condition is complicated.The peak regulation on the Three Gorges electricity station will inevitably lead to changes in water-flow conditions,thus causing adverse impact on navigation.According to the requirements of the topmost safety limit of ship model test,this paper analyzed changes of the maximal rudder-angle,the maximal drift-angle,the speed of ship opposite the bank and the navigation time of the fleets upstream and downstream navigation of different fleets at each key leg at peak regulation in flood season.Besides,the navigational conditions at peak regulation in flood season were demonstrated to ensure safe navigation of ships through this leg.The optimal route,navigation mode and difficult points of navigation were presented.
