摘　　要：以某地铁桥建合一高架车站为实例进行隔震结构计算分析。采用ETABS软件建立隔震结构模型,对隔震支座在罕遇地震下的水平位移,隔震支座最大剪力、轴力、压应力及其拉应力进行计算,并对高架车站隔震结构与非隔震结构的经济指标进行对比分析。结果表明,隔震结构计算结果满足规范要求,高架车站隔震结构比非隔震结构造价降低,具有更好的经济性,安全度大大提高。Taking an elevated metro bridge-station combined structure as an example,this paper calculates and analyzes the seismic isolation structure.It uses the ETABS software to establish the seismic isolation structure model and calculates the horizontal displacement of the isolation bearing under the rare earthquake,the maximum shear force,axial force,compressive stress and tensile stress of the isolation bearings,while it also compares and analyzes the cost effectiveness of the isolation structure and the nonisolation structure of the elevated station.The results show that calculation of the seismic isolation structure meets the standard requirements.The structure of the seismic isolation of the elevated station is lower than the non-isolation structure and has a better costeffectiveness while the safety is greatly improved.
