摘要
为了保障施工过程的安全,在文昌大桥的施工过程中,在主桥控制截面布设了应变计,对施工过程中结构的应力变化进行跟踪监测,为桥梁施工提供安全预警;为了保证成桥线形满足设计要求,对悬浇过程中的主梁挠度进行跟踪监测与控制,为施工提供立模标高,并通过合理设置预拱度来控制梁体线形。
This article discussed and summarized the stress control and displacement control method of this bridge. The construction control team installed strain transducer in the control sections to monitor the stress changes during the construction and provide the safety warning service. We also montiored the girder deflection during the casting periond to provide elevation,and set reasonable camber to control the girder alignment.
