摘　　要：近年来,我国交通工程发展迅猛,为降低新建工程对城市交通的干扰,提高施工效率和工程质量,节段梁预制拼装技术被广泛应用于桥梁工程。文章以五峰山大桥公路接线南引桥30 m跨连续预制箱梁拼装施工为例,着重分析节段梁拼装施工流程与技术要点,并提出了具体的施工质量控制要点,旨在为同类型节段梁施工提供经验和参考。In recent years, China’s traffic engineering has developed rapidly. In order to reduce the interference of newly-built projects on urban traffic and improve construction efficiency and project quality, segmental beam prefabricated assembly technology is widely used in bridge engineering.Taking the assembly construction of 30m-span continuous prefabricated box beam of south approach bridge of the highway connection of Wufengshan Bridge as an example,this paper focuses on the analysis of the construction process and technical points of segmental beam assembly, and puts forward specific construction quality control points, aiming to provide experience and reference for the construction of the same type of segmental beam.
