| 摘 要： | 以重庆鱼洞长江大桥为研究对象,建立了大跨度高墩连续刚构桥的空间计算模型,考虑群桩与桩土效应,分析其动力特性,并运用反应谱法与时程分析法计算了一致激励及下大跨连续刚构的地震响应。分析结果表明:该桥动力特性符合设计要求,其横向地震响应比纵向大,具有良好的抗震性能。

| Abstract: | Taking Chongqing Yudong Yangtze River Great Bridge for an example,the space calculation model of large-span high-pier continuous rigid frame bridge is established.Based on this,the dynamic characteristic of this bridge is analyzed considering group pile and soil interaction.Earthquake response of uniform excitation and large-span continuous rigid frame is calculated using response spectrum and time history analysis method.The result shows that dynamic characteristic of this bridge conforms to design require... |
