摘要
龙潭长江大桥为主跨1560 m的钢箱梁悬索桥,是连接南京与扬州仪征的重要过江通道。考虑“尺度、风格、标志、意象、实施”原则开展景观设计,以“青山绿水、龙潭卧波”为主题设计了独树一帜的“二龙戏珠”桥塔造型,实现桥梁与地理环境、地域文化的深度结合。文章总结项目在塔柱、异形上横梁、塔顶“龙珠”等施工中应用的关键技术与工艺创新,为大跨度悬索桥桥塔的设计与施工提供实践参考。
The Longtan Yangtze River Bridge is a steel box girder suspension bridge with a main span of 1,560 meters,serving as a crucial rivercrossing channel connecting Nanjing,Yizheng and Yangzhou.Guided by the principles of scale,style,landmark,imagery,and implementability,landscape design was carried out with the theme green mountains and clear waters,dragon resting on waves,creating a unique two dragons playing with a pearl tower shape that achieves deep integration between the bridge,geographical environment and regional culture.This paper summarizes key technologies and process innovations applied in the construction of tower columns,irregular upper crossbeams,and the dragon pearl at the tower top,providing practical references for the design and construction of towers for long-span suspension bridges.
