摘　　要：汕头市黄河路快速化升级改造工程的主线跨线桥工程横跨汕头市黄河路与天山路十字交叉路口,该路口属于国道与省道交汇口,交通车流量大,无法实行全封闭施工,且跨线桥钢-混叠合梁采用56m长大跨度超长钢梁,安装难度大。通过采用城市中心区超长钢-混叠合梁施工技术,主线跨线桥钢-混叠合梁安装可快速、安全地完成,在保证施工质量的同时,确保了跨线桥主体结构的完工时间。The main line overpass bridge of Shantou Huanghe Road rapid upgrading and reconstruction project crosses the intersection of Huanghe Road and Tianshan Road in Shantou City,which belongs to the intersection of national and provincial roads,the traffic flow is large,and it is impossible to carry out fully closed construction.Moreover,the steel-concrete composite beam of the overpass bridge is a 56m large span super-long steel beam,which is difficult to install.By adopting the construction technology of super-long steel-concrete composite beam in urban center,the installation of the steel-concrete composite beam for the main line overpass bridge can be completed quickly and safely.While,the construction quality and the completion time of the main structure for the overpass bridge is ensured.
