摘要

文章考虑土-结构相互作用影响,对土-地下车站结构系统的自振频率进行定量分析,计算了不同场地条件下车站的自振特性,得到了周围土体与车站结构的模量比和软土层埋深不同对土-地下车站结构系统自振频率的影响,得到的结果对于地下车站抗震设计具有指导意义。
The paper discusses soil-structure interaction,qualitatively analyzes the natural vibration frequency in the soil-structure system of underground stations,and calculates station vibration characteristics under different site conditions.The paper works out the surrounding soil modulus ratios and different pairs of soft soil depth and their impact on soil-underground stations vibration frequency.The conclusion is conducive to the anti-seismic design of underground stations.
