谈永川长江大桥钢-混结合段施工关键技术

摘要

Taking Yangze river bridge in Yongchuan as an example,the paper studies its bridge steel-concrete combined section construction dif-ficulties,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.%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。
