【摘要】：铁路钢箱拱连续梁桥具有结构受力性能好、跨越能力大、造型简洁美观等诸多优点,在桥梁建设中具有较强竞争力。铁路钢箱拱连续梁桥建造过程中受力情况变化多、施工阶段多、建设周期长、影响因素复杂,施工监控可有效避免成桥后偏离设计较远的情况,以保证其工程质量和使用安全。本文以(32+64+32)m铁路钢箱拱连续梁桥为工程背景,详细介绍了施工控制技术的理论和方法。采用Midas/Civil软件建立有限元模型,对桥梁施工过程中各主要施工阶段进行数值模拟,对桥梁结构受力及竖向变形情况进行分析并对现浇支架进行了检算。在理论分析的基础上,对此桥实施了现场监控并进行了理论与实测的对比。结果说明此次铁路钢箱拱连续梁桥施工监控是成功的,对今后类似桥梁的施工具有一定的借鉴意义。
[Abstract]:Railway steel box arch continuous beam bridge has many advantages, such as good structural mechanical performance, large span ability, simple and beautiful shape and so on, so it has strong competitiveness in bridge construction. During the construction of railway steel box arch continuous beam bridge, there are many changes in force, many construction stages, long construction cycle and complex influencing factors. Construction monitoring can effectively avoid deviation from the design after completion of the bridge, so as to ensure its engineering quality and safety. Based on the engineering background of (326432) m railway steel box arch continuous beam bridge, the theory and method of construction control technology are introduced in detail in this paper. The finite element model is established by using Midas/Civil software to simulate the main construction stages of the bridge, the stress and vertical deformation of the bridge structure are analyzed, and the cast-in-place support is checked and calculated. On the basis of theoretical analysis, the field monitoring of the bridge is carried out and the theoretical and measured comparison is carried out. The results show that the construction monitoring of railway steel box arch continuous beam bridge is successful and has certain reference significance for the construction of similar bridges in the future.
