摘要
南京江心洲大桥为主跨248 m的独柱塔空间缆索自锚式悬索桥,主鞍座的结构设计独特、空间受力复杂。介绍该桥主鞍座结构设计的要点,建立精细化有限元模型,得到空间主鞍座的传力路径和应力分布规律,为类似空间主鞍座结构设计与分析提供参考。
Nanjing Jiangxinzhou Bridge is a single-column-tower and spatial cable self-anchored suspension bridge,with the main span 248m.Structural design of the main saddle is unique,and special research should be done on its space structural analysis.First of all,to introduce the main points about structural design of the saddle,and refinement finite element model is established,by which its path of force transfer and stress distribution are obtained.The work can provide the appropriate reference on the similar saddle design and analysis.
