大跨度钢管混凝土拱桥施工技术研究

Research on construction technology of large span CFST arch bridge

介绍了大跨度钢管混凝土拱桥主要的施工方法,并以一个上承式钢管混凝土拱桥为例,利用大型有限元软件MI-DAS对该类拱桥进行了全桥数值模拟,分析了大跨度钢管混凝土拱桥拱上结构安装各阶段内力及变形情况,为同类大跨钢管混凝土拱桥的施工控制提供了一定指导。

This paper introduced the main construction methods of large span CFST arch bridge, and taking a deck type CFST arch bridge for example, used the large finite element analysis software MIDAS made numerical simulation to this kind arch bridge. Analysed the internal force and deformation in upper structure installation each stages of large span CFST arch bridge, provided some guidance for the eonstruction control of similar large spanCFST arch bridge.
