摘　　要：采用挂篮施工的连续梁桥,线形控制是保证成桥线形与设计线形相吻合的关键,其中施工测量又是直接影响线形控制结果。文中结合一座在建的城际铁路连续梁桥,通过施工测量控制技术进行桥梁线形控制,其最终成桥线形与设计线形相吻合,加快了施工进度,为同类桥梁工程施工提供参考。For the continuous beam bridges constructed with hanging basket,the alignment control is the key factor to ensure that the practical alignment is consistent with the design alignment,in which the construction survey directly affects the alignment control results.Combined with a continuous beam bridge of Intercity Railway under construction,the bridge alignment was controlled by construction measurement control technologies.The results show that the final bridge alignment is consistent with the design alignment,which accelerates the construction progress and provides reference for the construction of similar bridge projects.
