| 摘 要： | 基于大跨度连续梁桥的特点及某大桥施工时需要调整施工方法的实际情况,运用有限元分析软件,计算并比较了两种施工方法下结构受力情况及主梁线形变化状况。通过施工、设计及监控解决相关技术难点后,桥梁顺利合龙,并缩短了近1个月的工期,表明悬臂浇筑与支架现浇相接合这种施工方法是可行的。

| Abstract: | Based on the characteristics of large span continuous girder bridge and the modified construction methods according to the actual situation,this paper calculated and compared the force conditions of structure and the deflection of main girder by adopting two different construction methods and applying finite element analysis software.Through solving the construction,design,monitor and other related technical problems,the bridge closed smoothly and the construction period shortened nearly one month,which shows that construction methods as cast-in-cantilever connecting with cast-in-place are feasible. |
