摘　　要：PUSHOVER分析方法因其计算简单、力学概念清晰等特点,在桥梁抗震设计中已被广泛采用。在PUSHOVER分析中,横向荷载加载模式对结果的影响较大。通过一个双柱式桥墩横桥向PUSHOVER分析,并将结果与非线性时程分析结果进行对比,从而得到该类型桥墩较为合适的荷载加载模式。PUSHOVER analysis method is used widely in aseismatic design of bridge because of its simple calculation and clear mechanics concept,etc.Transverse direction load loading pattern will have larger influence on the results of PUSHOVER analysis.According to transverse bridge direction PUSHOVER analysis on some double column pier,the proper load loading pattern can be obtained by the results comparison of the PUSHOVER analysis and nonlinear time-history analysis.

关 键 词：桥梁抗震 PUSHOVER分析 双柱式桥墩 荷载加载模式
