| 中文摘要: |
| 宁波舟山港中部海域四面岛屿环抱，船舶只能通过几处航门进出。东侧的灌门和龟山航门船舶通航潮流条件、南侧的金塘大桥和西堠门大桥最大通航船型限定均较严格。通过对灌门和龟山航门水域的潮流观测，设定船舶依次排队通过工况对2处航门的航道通过能力进行分析，并对金塘和西堠门大桥的通航尺度和现行规范进行适应性分析，研究净空尺度起算面、船舶水线以上高度、桥梁坡度和挠度、桥梁净高和过路船舶水线以上最大高度实时测量系统。结果表明，灌门和龟山航门的通过能力与中部海域港口规划发展相适应。宜建立大型船舶过桥动态审批制度，从而起到释放水域岸线发展潜力的效果。 |
| 英文摘要: |
| The central sea area of Ningbo-Zhoushan Port is surrounded by islands on all sides,and ships can only enter and exit through a few navigation gates.The current conditions for navigation of ships at Guanmen and Guishan Navigation Gate on the east side,as well as the maximum navigation ship types for Jintang Bridge and Xihoumen Bridge on the south side are relatively strict.By observing the tidal currents in the waters of Guanmen and Guishan Navigation Gate,we set up the working conditions for ships to queue up in sequence,and analyze the passage capacity of the two navigation gates.Then we carry out the adaptability analysis of the navigation scale and current codes of Jintang Bridge and Xihoumen Bridge,and study the starting surface of clearance scale,the height above the waterline of ships,the slope and deflection of bridges,the net height of bridges,and the real-time measurement system of the maximum height above the waterline of passing ships.The results show that the passage capacity of Guanmen and Guishan Navigation Gate is suitable for the development of port planning in the central sea area.It is suggested to build a dynamic approval system for large ships crossing bridges,in order to unleash the potential for the development of water shorelines. |
