摘　　要：杭州湾跨海大桥航道桥包括南航道桥和北航道桥,南航道桥为主跨318 m的A形独塔双索面钢箱梁斜拉桥,北航道桥为主跨448 m的钻石形双塔双索面钢箱梁斜拉桥。介绍南、北航道桥的钢箱梁构造、结构体系、细部构造、结构计算和涂装方案等。The channel bridges of Hangzhou Bay Sea-Crossing Bridge include two bridges separately over the south and north channels. The south channel bridge is a steel box girder cable-stayed bridge with a main span 318 m, a single A-shape pylon and double cable planes, while the north channel bridge is a steel box girder cable-stayed bridge with a main span 448 m, two diamond-shape pylons and double cable planes . In this paper, the structures, structural systems, structural details, structural calculations and coating schemes of the steel box girders of both the south and north channel bridges are dealt with.
