摘要
为研究地震作用对地铁车站的影响,本文以郑州市轨道交通3号线地下标准车站为计算模型,按照反应位移法的理论,先求出地层相对位移、结构惯性力和结构与周围土层剪力,然后进行有限元计算。其中地层相对位移需要用EERA软件模拟地震波得出,采用SAP2000软件对不同计算结果进行对比分析和量化评判。最后,文中给出了地铁车站在地震作用下结构方案的设计建议,包括各控制部位的配筋率,对于类似工程具有一定的参考意义。
To study the seismic influence on metro station,the paper takes a standardized metro station on No.3 rail transit line in Zhengzhou province as the calculation object. With the help of response displacement method,it then works out the relative displacement of stratum,inertia force of the structure and the sheer forces of both,and performs the finite-element calculation. It needs to be noted that based on the seismic wave simulation of EERA software,the relative displacements of stratum arrive,which are then compared and analyzed by using SAP2000 software. In this light,the paper presents the seismic-resistant structural design of metro station with clearly-defined reinforcement ratio of control parts,which has a certain reference value for the similar projects.
