针对北京地铁隧道,采用弹性地基模型,以EI地震波为地震荷载,进行了平面有限元动力计算分析。该计算结果既可为相似的隧道设计提供一定的参考依据,也可为地下结构的抗震设计规范的修订提供一定的计算数据。
According to the Beijing subway tunnel, the elastic foundation model is used and the EI seismic wave is taken as the earthquake load. The plane finite element dynamic analysis is carried out. The results of the calculation can not only provide some references for similar tunnel design, but also provide certain calculation data for the revision of seismic design code of underground structures.
