连续梁桥悬臂浇筑施工变形控制

结合岳常高速公路某大桥现场施工监控实例，简要介绍连续梁桥悬臂浇筑施工的变形控制，通过采用前进倒退位移分析方法分析确定各个施工阶段梁体各节段变形值用以指导施工，以保证桥梁施工中的安全性，桥梁线形满足设计要求。

Deformation control of continuous bridge cantilever pouring construction

Combining with in-situ construction monitoring case of the bridge on Yue-Chang highway,this paper briefly introduces deformation control of continuous bridge cantilever pouring construction,determines beam joint deformation value during construction stage by adopting advancing-retreating displace analysis method,so as to guide construction and to ensure construction security and to guarantee the bridge linear to meet design requirements.
