随着城市桥梁旧桥维修加固改造工程的日益增多,桥梁同步整体顶升技术得到快速的发展,为了保证桥梁的结构安全,在桥梁顶升施工时进行施工监测是必不可少的环节。结合工程实例,对多跨连续曲线梁桥在顶升过程中的位移、应力进行监测研究分析,结果表明,采用同步顶升技术以及精细的施工监测,成功对多跨连续曲线梁桥进行了整体同步顶升,确保了桥梁结构的安全。
With the increasing number of repair and reinforcement projects of old bridges in urban bridges, the overall synchronization of bridge synchronization has been rapidly developed. In order to ensure the structural safety of bridges, construction monitoring during the construction of bridges is an essential step. Combined with engineering examples, the displacement and stress of multi-span continuous curved girder bridge during the ascending process are monitored and analyzed. The results show that using the synchronized ascent technology and the fine construction monitoring, the multi-span continuous curved girder bridge is successfully completed Synchronized rise, to ensure the safety of the bridge structure.
