摘　　要：广州丫髻沙大桥主桥为 76m +36 0m +76m 3跨连续自锚中承式钢管混凝土拱桥 ,跨越珠江南航道。对于特大跨度拱桥来说 ,如何减轻桥面结构的重量并增加其整体性是设计的关键 ,详细介绍该桥主桥桥面结构设计构思及主要细节 ,其桥面板、钢横梁及钢纵梁设计的理念对纵横梁体系桥面结构设计具有指导意义。The main bridge of Yajisha Bridge is a three span (76m+360m+76m) continuous self-anchored half-through Concrete-filled steel tubular arch bridge overpassing south navigation channel of Zhujiang River. For such an arch bridge with a super long span, how to reduce the weight of bridge deck and improve the integrity of the bridge is the crux of design. The paper describes in detail the structural design concept of bridge deck.
