根据京沪高速铁路庄前特大桥的结构特点,采用菱形挂篮悬臂法施工,通过对施工过程中桥梁结构各部分的变形量进行监测和控制,确保了施工过程中桥梁结构的合龙精度和成桥后结构的线形符合设计要求。该桥梁体外观线型流畅,施工方法简单,易于施工人员掌握。 According to the structural characteristics of Zhuangqian Bridge on Beijing-Shanghai high-speed railway, the bridge cantilever method is adopted to monitor and control the deformation of each part of the bridge structure during the construction so as to ensure the closing accuracy and reliability of the bridge structure during the construction The linear structure of the bridge conforms to the design requirements. The bridge body smooth appearance, construction method is simple, easy to grasp the construction staff.
