摘　　要：随着桥梁建设的发展,钢箱梁以其跨度大、自重轻、承载能力强,以及可后场预制拼装、现场安装节约工期的优点,广泛应用于跨海桥梁施工。以厦门第二东通道工程东侧非通航孔桥钢箱梁安装为例,对安装调位过程中的精度控制进行深入研究,具有为后续类似工程提供借鉴的意义。With the development of bridge construction, steel box girder is widely used in the construction of sea-crossing bridges due to its advantages of large span, light weight, as well as strong bearing capacity, and can be prefabricated and assembled on site to save construction time. Taking the erection and installation of the steel box girder of the channel bridge of Xiamen Second East Passageway Project as an example, the precision control in the process of installation and adjustment is studied in depth, which provides reference for subsequent similar projects.
