摘要
地铁结构抗震分析是地铁结构设计的重要组成内容。本文简要阐述三种抗震计算方法,将反应位移法理论应用于厦门市轨道交通1号线一期工程中山路西站车站结构的地震反应分析,计算结果表明:在中震作用下,车站的中柱轴压比未超过0.85的限值,结构最大层间位移比均小于1/550,可以认为结构处于弹性工作阶段,构件截面及配筋均满足抗震计算要求;在大震作用下,车站弹塑性层间位移未超过1/250的弹塑性层间位移限值,可以认为结构局部处于弹塑性工作阶段;最后提出抗震构造措施。本文研究方法和研究成果对地铁车站结构抗震设计具有指导意义。
The subway structure anti-seismic analysis is an important content of the subway structural design. Three aseismic calculation methods were briefly expounded in this paper,the response displacement method is introduced to the seismic response analysis of the west station at zhongshan road at the first phase of Xiamen metro line one. The results show that： the structure can be considered to be in the elastic stage,and the requirements of the member section and reinforcement for antiseismic calculation cart be satisfied with the action of moderate earthquakes based on the maximum displacement ratio of the structure layer which is less than 1/550 and the axial compression ratio of the central pillar which does not exceed the limit value of 0. 85;Under strong earthquakes, the elastic-plastic interlaminar displacement of the station which is less than the limit value of 1/250 shows the local structure is in the elastic-plastic stage ;the anti-seismic structural measures are put forward finally, in this paper,research methods and research results are significant for anti-seismic structure design of subway station.
