福州三县洲闽江大桥是一座主跨为 2 38m的独塔单索面预应力混凝土斜拉桥 ,其主跨采用悬臂拼装法施工 ,拼装过程中力求“索力”、“线形”双控 ,安装控制难度较大。介绍了该桥在悬拼施工过程中的监控阶段的确定、施工监控原则、监控计算、标准节段监控实施步骤、监控内容及监控效果。
Fuzhou Sanxianzhou Minjiang Bridge is a single tower single cable plane prestressed concrete cable-stayed bridge with a main span of 2 38m. The main span of the bridge is constructed by cantilever assembly method. During the assembling process, the “cable force” and “linear” double-control , Installation control is more difficult. This paper introduces the determination of the monitoring stage, the principles of construction monitoring, the monitoring and calculation, the implementation steps of the standard section monitoring, the content of monitoring and the monitoring results of this bridge during its construction.
