摘要
以某地锚式悬索桥为工程背景,通过建立悬索桥整体有限元模型及施工过程现场监测,对工程背景悬索桥的主缆施工及钢箱梁吊装施工过程的控制方法进行了研究。研究结果表明:悬索桥的几何非线性对于悬索桥的找形分析影响显著。所建立的悬索桥有限元模型可以较为准确的模拟工程背景悬索桥的施工过程。施工现场监测结果与有限元计算结果较为吻合,较好的指导了工程背景桥的施工。
A ground-anchored suspension bridge was selected as an example to study the construction control method of ground anchored suspension bridge. Based on the finite element model of suspension bridge and site monitoring of construction process,the construction control method of main cable construction and the steel box girder hoisting of suspension bridge was discussed. The conclusions are the finite element model of suspension bridge can accurately simulate the construction process of suspension bridge. The monitoring results of the site are in good agreement with the finite element calculation results,which can guide the construction of the project.
