枢纽互通钢混组合箱梁施工技术研究

Research on Construction Technology of Hub Interchange Steel-Concrete Composite Box Girder

文章结合张家界至南充高速公路工程,详细介绍了枢纽互通主线桥钢混组合箱梁的施工技术。对于枢纽互通主线桥,在实地考察现场施工条件的基础上,要切实考虑钢混组合梁的运输及安装对交通的影响,施工难度较大,文章总结出一套切实可行的适用于枢纽互通型的钢混组合箱梁施工工艺,可为同类工程提供借鉴和参考。

Combined with Zhangjiajie-Nanchong Expressway engineering,this paper introduces the construction technology of steel-concrete composite box girder of the main bridge of hub interchange in detail.For the main bridge of the hub interchange,on the basis of on-the-spot investigation of the construction conditions on the site,it is necessary to consider the influence of the transportation and installation of the steel-concrete composite beam on the traffic,and the construction is difficult.A set of feasible construction technologies of steel-concrete composite box girder suitable for hub interchange is summarized,which can provide reference for similar engineering.
