摘要
本文以珠海市横琴新区双向变截面、双向纵坡的钢箱梁斜拉桥的施工为例,详细介绍了斜拉加劲连续钢箱梁桥进行顶推施工的方案比选、前期准备、顶推流程、注意事项及钢箱梁落梁等,为同类钢箱梁桥的顶推施工提供参考。
Incremental launching method owns broad prospect because its safety, convenience, little inference with local environment, less occupied and other advantages. In this paper, the construction of a cable-stayed bridge with a two-way variable cross-section steel box girder in Hengqin district,Zhuhai was taken as the example. The preliminary preparation,the pushing process,the precautions and the box girder beam installation were introduce in detail, thus references were provided for similar bridge projects.
