| 摘 要： | 结合跨径220米的许沟大桥结构设计,通过对全桥有限元模型动力分析和通车动载试验,对钢筋混凝土拱桥全桥动力特性进行分析,并选用50年超越概率为3%的人工地震波和E l Centro波(调整至7度)进行时程分析。根据抗震分析的结果分析控制截面地震内力,并结合通车动载试验结论,对许沟大桥抗震性能做出综合评价,对大跨径钢筋混凝土拱桥抗震设计提出合理建议。

| Abstract: | Through the analysis of FEA model of the whole bridge and dynamic test of main span 220m Xu Gou bridge,the dynamic characters of reinforced concrete box rib arch bridge are analyzed,at the same time the seismic waves of 50 year exceedance probability of 3% and El Centro(be regulated to 7degree) are used for time history analysis of the structure.The results of the seismic analysis are compared with the real bridge dynamic test,usmich are used for determining key section seismic internal force,and the synthesis evaluation of the bridge seismic performance is carried out,thus the advices for arch bridge seismic design are put forward. |
