摘　　要：钢箱梁顶推施工技术作为道路桥梁工程施工中最主要的施工技术之一,该施工技术应用的合理与否对道路桥梁工程施工质量的优劣有着决定性影响。经过对江西胜利大桥钢箱梁顶推安装施工工艺的深入研究与实践运用,发现该工艺在钢箱梁拼装和顶推施工等方面具有得天独厚的优势,因此,建议在同类型桥梁施工中广泛推广和应用这一工艺,以期达到事半功倍的效果。采用这一工艺,不仅能提高施工效率,还能节约工程成本。As one of the most important construction techniques in road and bridge engineering,the steel box girder top pushing construction technology has a decisive impact on the quality of road and bridge engineering construction whether the application of this construction technology is reasonable or not.After in-depth research and practical application of the steel box girder top push installation construction technology of Jiangxi Shengli Bridge,it was found that this technology has unique advantages in steel box girder assembly and top push construction.Therefore,it is recommended to widely promote and apply this technology in the construction of similar bridges,in order to achieve twice the result with half the effort.By adopting this process,not only can construction efficiency be improved,but engineering costs can also be saved.
