摘　　要：文章以一座大跨径上承式箱型拱桥为例,通过阐述工程概况,建立成桥状态下的有限元模型,利用反应谱法和时程分析法计算分析其地震响应。结果表明,该桥抗震性能良好。Taking a long span deck-type box arch bridge as example,the article introduces the general information about the construction project. Through building a finite element model under completed status, the article analyzes and calculated the earthquake reaction by using response spectrum method and time history method.The result shows that this bridge has a good shock resistance.
