| 摘 要： | 应用反应位移法，有限元反应位移法和有限元动力分析方法，以兵库县南部地震的Port-Island观测波形作为地震动输入，对某给定地质条件下的浅埋箱型地铁结构进行了不考虑结构与土脱开滑移和考虑结构与土脱开滑移的两种情况的计算，通过计算可以了解到一般箱型结构与上脱开，滑移的位置和范围，计算结果表明，抗震设计时，在强地震作用下，结构与土的脱开，滑移作用考虑与否，对结构变形和断面力计算值的影响很大。

| Abstract: | By using the methods of response displacement, finite element response displacement and finite element dynamic analysis, the Port-Island wave of Hyoko Ken Nanbu (Kobe) earthquake was input to analyze the shallowly buried trunk subway structure with the considerations of slippage and coming away between the structure and soil under certain geological condition. The results indicate that considering the slippage and coming away between the subway structure and the soil or not will greatly influence the section stress under strong ground motions. |
