摘　　要：为检验向家坝升船机通航条件,协调部、省、市三级航运主管部门,明确实船试航工作流程及组织实施模式,对“船-机-水”相互适应性进行了枯水期、丰水期实船试航试验。结果表明,升船机及助导航设备设施性能良好,船舶安检调度及航路航法科学合理。泄洪工况下,下游引航道及口门区通航水流条件较差,对通航影响较大,研究应用“无人机+自动跟踪浮子”及“三维立体视觉”水流条件观测新方法,提出电站出流8500 m 3 s,泄洪不超2200 m 3 s双控通航流量标准,试航成果为后续升船机试通航运行及通航验收提供数据支撑。To evaluate the navigable conditions of the Xiangjiaba ship lift,we coordinate with the shipping authorities at ministerial,provincial,and municipal levels to define the work process and organization mode for seaworthiness tests of actual ships and carry out prototype tests of“ship-ship lift-water”mutual adaptability in the dry and wet seasons.The results show that the ship lift and facilities providing navigation aids are in good condition,and the scheduling of ship security inspection and navigation routes are scientific and rational.Under flood discharge conditions,the navigable flow conditions in the downstream approach channel and the entrance area are poor,which has a great impact on navigation.Hence,we develop and apply a new method of the“unmanned aerial vehicle(UAV)+automatic tracking float”and“three-dimensional(3D)vision”to observe flow conditions.We propose the dual-control navigable traffic standards of the outflow from the power station of 8500 m 3 s and the flood discharge of no more than 2200 m 3 s.The results provide data support for the follow-up trial operation and navigation acceptance of the ship lift.
