摘要
南京小龙湾大桥主桥采用44 m+96 m+44 m自锚式悬索桥,结构新颖,受力复杂.介绍该桥结构设计,并建立三维空间有限元模型,采用"弹性系数优化法"对其合理成桥状态进行研究.分析结果表明,该桥设计合理,采用的合理成桥状态确定方法能够有效体现设计者的意图.
Nanjing Xiaolongwan Bridge, the main part of which is a 44 ＋ 96 ＋ 44-meter self-anchored suspension bridge, is novel in structure and complex in loading. This paper introduces the structural design of this bridge, builds a three- dimensional finite element model, and studies the practical finished bridge state by employing elastic coefficient optimization method. The results of the structural analysis show that the design of this bridge is practical and the designer＇s intention can be reflected in the method used to determine the viable finished bridge state.
