摘要： 研究大跨度上承式钢管砼拱桥在地震激励作用下的响应特性．对比了中、上承式钢管砼拱桥的自振特性，采用 时程分析法分析了纵向、竖向、横向激励作用下，上承式钢桁拱桥的响应特性，讨论了多点激励对上承式钢管砼拱桥 地震响应的影响，并与中承式钢管砼拱桥的地震响应特性进行了对比分析．

关键词: 拱桥, 钢管砼拱桥, 地震响应, 多维激励, 多点激励

Abstract: Seismic response behaviors of long-span concrete filled in steel tube(CFST)deck-type arch bridge were investigated.The free vibration specialty between half-through CFST arch bridge and CFST deck-type arch bridge was contrasted.The seismic response behaviors of CFST deck-type arch bridge subjected to longitudinal excitation，vertical excitation and lateral excitation were analyzed by time-history analysis method.The effect of multi-support excitation was also discussed，and the seismic response specialty was contrasted between CFST deck-type arch bridge and CFST half-through arch bridge.

Key words: arch bridge, CFST arch bridge, seismic response, multi-dimension excitation, multi-support excitation
