嘉绍大桥预应力混凝土连续梁挂篮施工方法

Concerning on construction method of prestressed concrete continuous girder cradle on Jiashao Bridge

结合嘉绍大桥预应力混凝土连续箱梁施工,详细介绍了箱梁0号块的施工,以及挂篮的结构设计,并探讨了箱梁悬臂浇筑线形和挠度控制,最后介绍了合龙段施工控制,对同类桥梁工程项目具有一定的指导意义。

Integrating with prestressed concrete continuous girder cradle construction on Jiashao Bridge,this thesis specifically introduces the construction of box girder blocks 0 # and structural design of cradles,and probes into the box and girder cantilever linear deflection and control,and finally,expounds the construction control of closure segment.Thus,it has certain directive significance for similar bridge project.
