摘　　要：金台铁路罗桥跨台金高速公路特大桥全长766.825m,在DK11+687~846处跨越台金高速公路,即上跨墩号为10#~11#墩,跨度为156m。本文重点介绍了特大桥的施工重难点及其系梁支架、窄桥面土字型支架、拱肋拼装、泵送顶升拱管混凝土、吊杆安装及张拉等施工关键技术,并作出了方案评估,为类似工程施工可提供经验参考。The Jintai Railway Luoqiao Bridge spans the Taijin Expressway Special Bridge with a total length of766.825m, and crosses the Taijin Expressway at DK11+687~846, that is, the upper span pier number is 10#~11#pier, and the span is 156m. This paper focuses on the construction difficulties of the special bridge and its key construction technologies such as beam supports, narrow bridge deck earth-type brackets, arch rib assembly,pumping jacking arch concrete, boom installation and tensioning, and makes a program evaluation, which can provide experience reference for similar engineering construction.
