京沪高铁跨沪宁高速公路特大桥施工监控技术

The construction monitoring technology of Beijing-Shanghai high-speed railway across Shanghai-Nanjing highway super bridge

以某铁路拱桥施工工程为例,介绍了主要施工监控阶段的控制手段,并从吊杆拉力优化、桥面线形测量、吊杆内力测量等方面,分析了桥梁线形监控中的技术要点,从而保证拱桥的施工质量。

Taking a railway arch bridge construction engineering as an example,this paper introduced the control method of main construction monitoring phase,and from the derrick tension optimization,bridge alignment measurement,derrick internal force measurement and other aspects,analyzed the technical key points in bridge linear monitoring,so as to ensure the construction quality of arch bridge.
