| 摘 要： | 针对3类不同的典型场地条件下的单层双跨地铁车站结构,采用土-地下结构整体动力时程分析方法,分析了地震动水平输入时峰值位移和峰值速度差异对地下结构地震反应的影响。结果表明,地震动峰值速度差异对地下结构地震反应的影响,在硬土场地条件下较大,中硬场地条件下次之,软土场地条件下最小;地震动峰值位移差异对不同场地条件下的地下结构的地震反应无明显影响。

| Abstract: | In this paper an integral dynamic time history method for soil-structure system is applied to study the dynamic response of a one-story two-span subway station in three typical sites. The influence of peak displacement and peak velocity on the seismic response of the station structure are analyzed through mathematical statistics. The results show that the change of PGV has great effect on the seismic response of underground structures for a hard site, mediate effect for mid-hard site, and minor effect for soft site. The change of PGD has no clear effect on the seismic response of underground structures for different sites. |
