摘要
以(60+100+60)m连续梁为研究对象,用有限元软件建立了该桥考虑桩土效应作用的全桥模型,采用反应谱法及时程分析法分析结构地震响应,并对其结果进行比较,同时分析基础刚度对地震反应的影响,结果表明基础刚度对桥墩地震反应影响较大。
This paper studies continuous bridge on a span of(60+100+60)m,the finite element software was used to build the whole model that considering pile-soil-stucture interaction.The spectrum response method and the time-history analysis were adopted to calculate the seismic response.The result were compared in detail and the influence of foundation stiffness for seismic response was analyzed,the result shows that the foundation stiffness has more influence on seismic response of pier.
