摘　　要：厦门第二东通道工程海中段桥梁上、下部结构均采用预制装配化方案,上部主梁采用90 m/150 m两类跨径的连续钢箱梁,桥面宽37 m。对海中段桥梁上部结构的方案选型和构造设计进行分析,如腹板及加劲板构造、正交异性桥面板构造及现场连接方式设计等进行了详细分析,可为同类型桥梁的设计提供参考。The superstructure and substructure of the marine bridge of Xiamen Second East Passage Project adopt the prefabrication and assembly-in-situ solution. The main girders are continuous steel box beams with two types of span length 90 m/150 m, and the bridge deck is 37 meters wide. In the paper, the scheme comparisons and structure design of marine bridge superstructure are analyzed in terms of web and stiffening plate structure, orthotropic bridge deck structure and field connection design, which can provides reference for design of the same type bridges.
