- 本文介绍了管拱桥跨越施工的工艺流程、管拱桥的预制、吊装及注意事项。吊装后的两座管拱桥轴线平面最大偏差分别为1.5mm和1.0mm,拱高与预制高度相同。证明管拱桥整体预制、一次吊装就位的施工方法工艺过程简单、劳动强度小、施工质量易于保证。
This paper introduces the technology procedure, prefabrication, suspending, installation and other noticeable items for crossing construction of pipe arch bridge. The axial plane deviation of the two pipe arch bridges are 1.5mm and 1.0mm respectively.Arch height is the same as that prefabrication. It proves that the construction method of ensembleprefabrication and installation in one step has the advantages of simple technology procedure, low labour intensity and ensuring of construction quality.1990,3(3): 43-45 收稿日期：1989-11-23
