大跨径混凝土连续梁桥施工精细控制方法

结合具体工程实例，介绍了大跨径混凝土连续梁桥施工控制的方法和内容，采用有限元软件对全桥各施工阶段进行仿真模拟分析。通过对现场相关参数进行识别、修正，计算出每一施工阶段结构理想状态，对桥梁施工过程中的结构安全、线形及应力进行有效控制，确保最终的成桥状态符合理论设计状态。

Fine Control Method of Long Span Concrete Continuous Girder Bridge Construction

Combined with the specific proj ect example,this paper introduced long span concrete continuous girder bridge construction control methods and content.The finite element simulation analysis was used for each construction stage of whole bridge.By identification,correction parameter of the field,each construction stage of ideal state was cal-culated.This effectively control the stress of structural safety,and the bridge construction process,to ensure bridge in-to the final state which is consistent with the theoretical design.
