地铁车站抗震性能研究
|
摘要
结合天津地铁1号线下瓦房车站实际工程,使用ANSYS程序建立黏性边界的有限元计算模型,运用模态叠加法对地下结构—土动力相互作用系统进行分析计算,得出了地铁车站框架结构在天津波、人工波(中震)及EI波作用下的地震反应(动内力、动位移).对现行结构设计进行校核,分析了结构抗震的薄弱环节以及地震反应可能对地铁车站造成的破坏.
In connection with the practical project of Xiawafang station of Tianjin subway Line 1,the paper established a finite element method model with stringy boundary by using ANSYS program,and analysed the dynamic interaction system of underground structure-soil based on the mode superposition method,obtained seismic responses(including dynamic internal force and dynamic displacement) of the subway station frame under the action of Tianjin wave,artificial wave(in shock) and EI wave.The structure design is tested and possible damage to subway station brought about seismic response is analyzed.
