摘要
钢箱梁已经成为现代大跨径桥梁设计的主要结构形式。不同于传统的施工环境,在海中进行钢箱梁安装要综合考虑多方面的影响因素。青岛海湾大桥是在我国北方冰冻海域修建的第一座大型海上桥梁集群,介绍了其沧口航道桥海中钢箱梁大节段吊装临时支架法的设计。
Steel box girder has been the main structure in modern large span bridge design.Unlike the traditional construction condition,installation of steel box girder in sea should consider many influence effectors synthesized.Qingdao Bay Bridge is the first bridge group in frozen sea in north of China,this paper introduced the temporary support design of steel box girder large segments lifting in sea of Cangkou Channel Bridge.
