摘要
装配式结构正逐步应用于地下工程中,其抗震性能是影响结构长期使用的关键因素。以某地区装配整体式地铁车站实际工程为背景,采用反应位移法,反应加速度法,惯性力-位移法以及动力时程分析法对装配整体式地铁车站进行地震响应分析。计算结果表明:不同计算方法的结果均有所差距,车站内力和变形较为接近,但与动力时程分析结果差距较大,尤其是车站侧墙的内力差距最为明显。车站在E2地震作用和E3地震作用下的最大层间位移角分别为1/850和1/390,远小于规范1/250的要求。
The assemble structure is being gradually applied to underground structures and its seismic performances were of crucial importance for the long-term use. Based on the actual project of monolithic precast concrete subway the response displacement method response acceleration method inertia force-displacement method and the dynamic time history analysis method were used to analyze the seismic response of station. The seismic responses of station were different according to use different seismic analytical method. The internal force and deformation of the station calculated by the practical analysis method are close but the calculated results between the practical analysis method and the dynamic time history analysis was large especially the internal force distribution of the sidewall of the station. The maximum lateral story drift angle under the action of E2 earthquake and E3 earthquake are 1/850 and 1/440 respectively which is less than the specification requirements of 1/250.
