摘要
采用土-结构相互原理对南京市典型双层地铁车站进行了水平地震作用下的有限元动力时程分析。结果表明,地震作用下结构的构件节点与中柱处应力最大,结构峰值变形反应与自由场峰值变形反应之间特性基本相似并近似存在简单的线性关系。讨论地震作用下土-地下结构体系动力响应的特点和影响因素,提出了一些地下结构抗震设计的参考建议。
Based on the basic theory of soil-structure interaction, a finite element model for the analysis of NanJing Double-deck Subway Station dynamic interaction is built, Time-history seismic analysis is used to calculate earth-quake response of this structure. The analyzed result shows that the larger shear forces , which were caused by hori-zontal ground motion, resulted in damage of the whole structure station. Several advices of the aseismic design of buried structures are given in conclusion.
