摘　　要：为研究适用于悬挂式单轨的大跨度桥梁,依托武汉光谷空轨旅游线项目,研究悬挂式单轨25 m+60 m+25 m系杆拱桥。以“一桥一景”为设计理念确定主桥景观,对主桥支承体系、主梁横断面布置形式、拱肋、桥墩细部构造等内容进行设计研究,并对主桥进行静力、抗震和车桥耦合分析,结果表明,主桥的刚度、强度和稳定性满足设计要求,乘坐舒适性优秀。In order to study the applicability of large-span bridges for the suspended monorail train,a tied arch bridge with the span of(25+60+25)m is researched for the suspended monorail train.The bridge was designed by the concept of“one bridge,one scenery”.Design and research were conducted on the support system of the bridge,the section of the beam,the arch ribs,and the detailed structure of the bridge piers.The static,seismic,and vehicle-bridge coupling analyses of the bridge were performed.The results show that the stiffness,strength,and stability of the bridge meet design requirements,with high ride comfort level.
