摘要

常规的建筑结构抗震设计认为地下结构受地震力作用较小,一般仅采取抗震构造措施,或者把地下结构等同于地面结构进行抗震验算。基于MIDAS/Gen软件对广州市珠江新城城市地下空间工程建立二维有限元模型,探索在土与结构之间采用弹性边界元,对结构进行抗震分析;并与不采用弹性边界元的同一结构进行了对比分析,得出对地下结构进行抗震计算是非常必要的。
Conventional seismic design of building structures considers that underground structures subjected to earthquake force is small,generally only to take details of seismic design,or the checking of earthquake resistance for the underground structure is equivalent to the surface structures.Based on MIDAS/Gen for urban underground space engineering of Guangzhou Zhujiang New Town,two-dimensional finite element model is established,explore to take the elastic boundary between the soil and underground structure,seismic analysis for the structure;and compared to the same structure with non-elastic boundary,the seismic calculation for the underground is necessary.
