摘　　要：文中以姑嫂树公跨铁立交桥为例,对跨铁路立交桥高位转体施工技术在该项目的应用进行分析。结果表明,姑嫂树跨铁路在建立交桥采用该方式顺利实现合龙,创造了亚洲立交桥第一例高空转体施工以及施工难度最大的纪录。合龙过程中,还能确保立交桥下方铁路交通不受影响,这是武汉首次在桥梁墩顶上方开展的大吨位混凝土箱梁转体施工尝试。This paper takes Gushao Shugong cross-railway overpass as an example,and analyzes the application of the construction technology of the cross-railway overpass with high rotation in the project.The results show that the flyover under construction in Gushao Shu-span railway successfully realized closure in this way,setting a record of the first high-altitude rotary construction and the most difficult construction in Asian flyover.In the process of closure,the railway line under the overpass is open to traffic as usual,which is the first large-tonnage concrete box girder rotating construction on the top of the bridge pier in Wuhan.
