摘　　要：针对目前钢管混凝土拱桥跨径不断增大,其施工难度和精度要求越来越高的情况,分别从工厂管节加工线型控制和现场架设定位线型控制等方面来阐述大跨径钢管混凝土拱的施工定位技术,以保证大跨径钢管混凝土拱桥施工质量。According to the increasing span of the steel pipe concrete arch bridge and the higher construction difficuhies and the accuracy, the paper illustrates the construction location technique of the large-span steel pipe concrete arch from the line-style control of factory pipe process and field erection location line-style control, so as to ensure the construction quality of the large-span steel pipe concrete arch bridges.

关 键 词：钢管混凝土拱桥 线型控制 定位技术
