| 摘 要： | 结合新建铁路贵阳至开阳南江特大桥悬臂施工监控实践,介绍了高墩大跨连续刚构桥的施工监控理论。采用有限元软件建立该桥的有限元计算模型,对该桥各施工阶段的主梁挠度及应力进行了仿真模拟分析,并在施工监控中对比分析计算数据与实测数据,以期指导施工并为同类型桥梁的施工控制提供参考。

| Abstract: | Combined with cantilever construction control practice for the Nanjiang bridge on the line of the newly built railway Guiyang to Kaiy- ang, the theory of the construction monitoring of high pier long-span continuous rigid frame bridge is introduced. Finite element analysis software is adopted to establish the finite element calculation model of the bridge. Deflection and stress of each construction stage is calculated on the sim- ulation analysis, and the calculated data and the measured data is compared, which guide the construction and provide reference for the same type bridge construction control. |
