摘　　要：拱桥是现代大跨度桥梁的主要桥型之一,其优点是跨越能力强,可承受更大的荷载,设计构思多样化。随着施工技术的发展进步,拱桥的跨度不断加大,对测量控制技术的要求也越来越高。本文笔者就依托建设中的拱桥为例,阐述拱桥施工过程中测量控制的方法,如何对拱桥挂篮拱圈施工的各个节段的高程及平面位置进行系统控制及对各个施工阶段监控量测的技术控制,使拱圈顺利合龙,拱桥桥面线形符合设计要求。Arch bridge is one of the main bridge types of modern long-span bridge.Its advantages are strong crossing ability,can bear greater load,and diversified design ideas.With the development and progress of construction technology,the span of arch bridge is increasing,and the requirements of measurement control technology are becoming higher and higher.In this paper,the author is relying on the construction of the arch bridge as an example,in the process of arch bridge construction measurement control method,how to arch arch construction of each section of the elevation and plane position system control and technical control of each construction stage monitoring measurement,make the arch ring,arch bridge deck alignment conform to the design requirements.
