摘要

混合箱梁斜拉桥在铁路行业应用越来越广泛,此文以新建广州南沙港铁路项目中跨某水道桥主跨(60+60+70+448+70+60+60)m混合箱梁斜拉桥为例,探讨其主跨结构型式、总体施工方案,同时研究边跨钢梁架设方案,提出整节段纵横向移动、节段顶推2种施工方案,并对边跨2种施工方案进行技术经济条件比较,拟定出科学合理的施工方案,为类似工程提供借鉴。
        The hybrid box girder cable-stayed bridge has been widely used in railway construction. Taking the hybrid box girder cable-stayed bridge across a waterway of Nansha port railway project in Guangzhou as an example,the structure type of main span and the overall construction plan are discussed. At the same time,the erection plan of side span steel girder is studied,and two construction schemes of vertical and horizontal movement of whole section and segment pushing are put forward. And the technical and economic comparison of two construction schemes of side span are carried out to draw up scientific and reasonable construction plan,which can provide reference for similar projects.
