谈永川长江大桥钢—混结合段施工关键技术

Discussion on critical construction techniques of steel-concrete combined section of Yangze river bridge in Yongchuan

以永川长江大桥为例,对该大桥钢—混结合段的施工难点进行了研究,从钢梁存梁支架、桥面吊机、钢箱梁定位等方面论述了钢—混结合段施工的关键技术,为类似工程的施工积累了经验。

Taking Yangze river bridge in Yongchuan as an example,the paper studies its bridge steel-concrete combined section construction difficulties,and discusses critical steel-concrete combined section construction techniques from aspects of steel-beam bracket,deck hoister and steel box girder orientation,which has accumulated construction experience for similar engineering.
