摘要
广州市轨道交通十四号线高架桥梁标准段在国内创新首次大规模、长距离采用节段预制拼装连续刚构形式,上部结构采用预制节段拼装组合箱梁,下部结构采用薄壁墩。介绍了现浇法结合短线法节段预制梁胶拼、整孔架设、湿接缝及后浇段浇筑、整联箱梁预应力张拉的施工方法,为今后类似工程的施工提供借鉴。
The superstructure of subway line 14 of Guangzhou city rail transit is designed as continuous precast sections that are used past technology on the long-distance viaduct of a large scale,which structure system is continuous rigid frame and thin-wall piers.This paper introduces a construction method that cast-in-place method combined with short line method past technology,followed full-span erection the pouring of wet-joint and post-casting section and full box girder prestressed tensioning,which offers reference for similar works.
