桥梁钢箱梁顶推施工过程存在的困难及其对策

Difficulties Existing in Incremental Launching Construction of Steel Bridge Box Girder and Its Countermeasures

以实际工程为例,对桥梁钢箱梁顶推施工中的施工难点进行了分析,然后从施工平台的施工、拼装平台的施工、钢导梁的安装、钢箱梁顶推施工等几个方面对桥梁钢箱梁顶推施工措施进行分析和探讨,为其它桥梁钢箱梁顶推施工提供理论支持。

Taking a practical project as an example,the article analyzes the construction difficulties in the incremental launching construction of steel box girder of bridge,and analyzes and discusses the incremental launching construction measures for steel box girder of bridge from the construction of construction platform,the construction of assembling platform,installation of steel guide beam and incremental launching construction of steel box girder,which provide the theoretical support for the incremental launching construction of the steel box girders of the other bridges.
