摘　　要：长江上游老虎梁滩段是重庆—宜昌河段内的重点碍航滩险,近期发生多起海损事故,严重影响船舶通航安全及航运效益发挥。针对此问题,采用物理模型试验和船模试验的研究手段,在深入揭示老虎梁滩段碍航水流特性及行船安全问题的基础上,对不同航道整治方案实施后的水流条件、行船状态进行了对比研究。结果表明,方案实施能减弱不良流态对船舶安全航行的影响,综合分析比选后推荐了最优方案,为该滩段航道整治工程设计提供科学依据,也可供其它类似滩险的航道整治研究参考。Laohuliang Beach in the upper Yangtze River is a major navigation-obstructing shoal from Chongqing to Yichang reach.Several marine accidents have occurred recently,which seriously affect the safety of navigation and shipping efficiency.In view of the above problems,this paper performs a physical model test and a ship model test.On the basis of deeply revealing the navigation-obstructing flow characteristics and navigation safety problems of Laohuliang Beach,the paper compares and studies the flow conditions and navigation states after the implementation of different channel regulation schemes.The results show that the schemes can reduce the influence of bad flow patterns on the safe navigation of ships.After comprehensive comparison,the optimal scheme is put forward,which provides a scientific basis for the design of channel regulation projects on this beach and can be used as a reference for other similar channel regulation research.
