桩土相互作用对大跨度桥梁抗震的影响
The influence of pile-soil interaction on the anti-earthquake of big-span bridges
【摘要】 以黑冲沟大桥为模型,采用了地震反应谱分析方法和弹性时程分析方法对其进行了地震反应分析以确定桩—土相互作用对大跨度桥梁地震反应的影响,并得出一些对设计和施工都有指导意义的结论。
【Abstract】 To make sure the influence of pile-soil interaction on anti-earthquake action of big-span bridges,the thesis makes an earthquake action analysis to Heichonggou Bridge by applying seismic response spectrum analysis and elastic time-history analysis,and makes the conclusions that are meaningful to both designs and constructions.
