基于桥梁顶推施工的导梁控制技术研究与应用
|
摘要
在桥梁推进施工中,导向梁起到减小主梁内力,增大跨距的作用。导梁的结构合理与否对整个推送施工具有重要意义。以高架桥上跨方式跨越汉宜高铁项目的顶推施工依托,运用Midas Civil有限元软件,根据施工图纸对临时结构与永久结构在不同工况的条件下整体建模计算,对混凝土连续箱梁顶推施工导梁控制技术进行分析研究,从而为类似工程提供借鉴。
In the bridge construction, the guide beam plays a role in reducing the internal force of the main beam and increasing the span. The reasonable structure of the guide beam is of great significance to the entire push construction. Using the overhead construction of the high-speed rail project of the Hanyi High-speed Bridge across the viaduct, Midas Civil finite element software was used to calculate the overall structure of the temporary structure and the permanent structure under different working conditions according to the construction drawings. Pushing the construction guide beam control technology for analysis and research, in order to provide a reference for similar projects
