近年来,随着城市轨道交通建设的快速发展,国内外对地铁车站的抗震分析研究也越来越重视,但现行的抗震分析方法都存在不同程度的局限性,导致用不同方法计算得出的结果存在很大差异。本文基于大型通用有限元计算软件ABAQUS对济南市典型地铁车站结构地震动力响应进行了系统的数值模拟计算与分析。并与传统的抗震简化方法反应位移法和静力分析等计算结果比较,分析了典型地铁车站在在地震作用下的动力响应特征,并讨论了车站考虑地震工况时的配筋设计,为提高地下轨道交通建筑抗震设计水平、改进地铁车站建筑抗震设计方法提供了依据。
In recent years, with the rapid development of urban rail transit construction, more and more attention is paid to the seismic analysis of metro stations at home and abroad. However, the existing methods of seismic analysis have different limitations, resulting in different calculation methods The result is very different. In this paper, based on the large-scale general finite element software ABAQUS, the dynamic response of the typical metro station in Jinan is simulated and analyzed systematically. Compared with the traditional method of seismic response reduction and static analysis, the dynamic response characteristics of typical metro stations under earthquake are analyzed and the reinforcement design of stations considering seismic conditions is discussed in order to improve The design of anti-seismic design of underground rail transit buildings and the method of seismic design of metro station buildings are provided.
