摘要
通过反应谱及有限元分析方法,对高烈度地震区公路隧道在衬砌刚度材料变化时的地震反应,采用3种工况分析,其计算结果与震害区公路隧道情况调研吻合,为高烈度地震区公路隧道设计提供参考。
Through the response spectrum and the finite element method to Seismic response of high -intensity earthquake area of Material changes in lining stiffness of highway tunnel, use the Three conditions analysis, calculated results and the research of earthquake disaster area is consistent, the result of high - intensity earthquake area in highway tunnel provide a reference for the design.
