香港青龙大桥初步设计方案受力分析

Analysis of Preliminary Design Program of Hongkong Tsing Lung Bridge

根据悬索桥的受力特点 ,将空间杆系与三维应力仿真分析模型相结合 ,给出大跨径悬索桥的三维应力有限元分析方法 .并运用这种方法对主跨 1418m的香港青龙大桥初步设计方案进行了受力分析 ,分别给出了整体结构受力分析和主梁。

In this paper,an analytical method is presented,in which 3 D bar model is combined with 3 D FEM Model to analyze the bridge according to its mechanical characters.Stress analysis of Hongkong Tsing Lung Bridge is completed with this method,and the methods of entire structure analysis and local stress analysis of main beam and saddle are given.
