摘　　要：文章介绍了双柱式桥墩Pushover分析的基本原理和操作步骤,通过计算实例对桥墩弹塑性数值模型的参数取值和分析结果进行了探讨。结果表明,一次迭代分析即可得到满足设计规范要求的合理水平力,从而获得双柱墩横桥向抗震容许位移。This article introduces the basic principles and operational steps of Pushover analysis for double column bridge piers,and explores the parameter values and analysis results of the bridge pier̓s elastic-plastic numerical model through calculation examples.The results indicate that a reasonable horizontal force that meets the design specifications can be obtained in one iteration analysis,thereby obtaining the seismic allowable displacement of the double column pier in the transverse direction of the bridge.
