预应力混凝土连续梁桥主桥施工阶段的监测

Monitoring of the Main Bridge of Pre-stressed Concrete Continuous Beam Bridge in Construction Stage

以某预应力混凝土连续梁桥的悬臂施工过程为背景,通过对连续梁桥施工阶段进行仿真分析和各节段的线形和应力控制的现场监测,保证桥梁施工过程的安全和顺利合龙,并使成桥后线形符合设计要求。

This paper took some prestressed concrete continuous girder bridge in the process of cantilever cast-in-place construction as the background.It could ensure the safety of the bridge construction process and made the linetype of the final bridge meet the design requirement successfully after through the construction stage of continuous girder bridge simulation analysis and each segmental linear and stress control field monitoring.
