悬臂浇筑梁桥合龙段施工临时锁定布置与计算

摘要

In light of temporary joint in the construction at cantilever grouting prestressed bridge closure section,combining with the construction of Wenguantun Bridge（60＋100＋60）m on Ha-Da passenger special line crossing cantilever grouting prestressed continuous concrete bridge,the paper describes the stress analysis and calculation,and discovers the rigid skeleton analysis differences of continuous bridge and continuous steel bridge as well.%针对悬臂浇筑预应力梁桥合龙段施工中临时联结问题,结合哈大客运专线文官屯特大桥（60＋100＋60）m跨悬臂浇筑预应力混凝土连续梁施工对其受力分析与计算作以阐述,并揭示了连续梁桥与连续刚构桥劲性骨架受力分析的不同之处。
