针对以往大都以单墩为模型进行桥墩抗震性能分析的问题,以墩—桩整体结构为计算模型,考虑动水压力的影响,分别采用增量动力分析方法和静力弹塑性分析方法分析了某跨海大桥的整体抗震性能,得到了桥梁结构的基底剪力—墩顶位移关系曲线,并以增量动力分析方法的结果为基准,研究了静力弹塑性分析方法用于墩—桩结构抗震设计的可靠程度。结果表明,静力弹塑性分析方法可准确、简明地评估桥梁结构的抗震性能,可满足工程要求。
Aiming at the problem of seismic performance analysis of bridge pier with single pier as a model in the past, taking the overall structure of piers and piles as the calculation model and considering the influence of hydrodynamic pressure, the incremental dynamic analysis method and the static elasto-plastic analysis method Based on the overall seismic performance of the sea-spanned bridge, the displacement curve of the basement shear-pier top of the bridge structure is obtained. Based on the results of the incremental dynamic analysis method, the static elasto-plastic analysis method is applied to the seismic response of the pier-pile structure The reliability of the design. The results show that the static elasto-plastic analysis method can accurately and concisely evaluate the seismic performance of bridge structures and meet the engineering requirements.
