摘　　要：以南渡江航道主桥为背景,详细介绍了超宽幅中央拱肋系杆拱桥方案的设计构思、总体布置、结构设计和计算。该桥跨径布置为单跨150 m,桥面宽度41.5 m。拱肋采用中央拱肋,并在1/4跨处分叉为双拱,双拱中间采用横撑连接,吊杆采用了中央索面编花布置,主梁采用全闭合钢箱梁。拱肋、吊杆、主梁(系杆)共同组成结构体系,共同承受荷载,并在景观造型上构造“空中半月”。This article takes the main bridge of Nandujiang Bridge as the background,which details the design concept,overall layout,structural design and calculation of the ultra-wide central arch rib tied bridge solution.The bridge span is arranged to a single span 150 m.In the design,the arch ribs use the central arch rib,and the one-fourth span is divided into two arches.The two arches are connected in the middle of the double arches.Beam,arched ribs,booms,and main beams(tie rods)together form a structural system,jointly bear the load,and construct a"half moon in the air"in the landscape shape.The meaning is far-reaching.
