摘　　要：由于大跨度钢桁架拱桥本身结构较为复杂,对于施工的要求较为严格,一般建设周期往往需要数年的时间,在桥梁建设施工阶段有遭遇地震的可能,因此,对大跨度钢桁架拱桥的抗震性能进行研究非常重要。论文在国内外专家学者研究成果的基础上,结合大桥建设的实际工程,对桥梁的动力特性以及抗震性能做了一些分析和研究,希望能够为我国今后大跨度钢桁架拱桥的建设提供一些借鉴经验。As the structure of long-span steel truss arch bridge itself is more complex,the construction requirements are more strict,the general construction cycle often takes several years,in the bridge construction stage may encounter earthquake,therefore,it is very important to study the seismic performance of long-span steel truss arch bridge.Therefore,on the basis of the research results of experts and scholars at home and abroad,combined with the practical engineering ofbridge construction,this paper has done some analysis and research on the dynamic characteristics and seismic performance of the bridge,hoping to provide some experience for the construction of large-span steel truss arch bridge in China in the future.
