摘　　要：地铁运行产生的环境振动超过一定值会影响人体健康,准确评价地铁运行引起的振动响应值意义重大。本文采用进口测振仪分别对青岛地铁3号线和上海地铁10号线进行现场测振,对数据进行处理得出振动加速度时程曲线,对测试数据进行Fourier变换得到相应的频谱曲线,将频谱曲线按1/3倍频程滤波转化为1/3倍频程谱,进而计算出分频振级平均值。通过加速度时程、频谱、1/3倍频程谱和分频振级的对比分析,结果表明:青岛地铁振动响应明显大于上海地铁,其分频振级已超过我国的环境振动标准,而上海地铁的分频振级基本上与我国的环境振动标准相当。The environmental vibration caused by subway running can affect human health if it exceeds a certain value.Evaluating the exact vibrational response caused by the subway is of great importance.Therefore,an imported vibration meter is used to measure the vibration of Qingdao Metro Line 3 and Shanghai Metro Line 10,respectively.By processing the data,the time-history curves of vibration acceleration are obtained,and the Fourier transform also obtains the corresponding spectrum curves.The spectrum curves are then transformed into the frequency range of the one-third octave spectrum.Finally,the average value of frequency vibration levels is worked out.The differences between Qingdao Metro Line 3 and Shanghai Metro Line 3 in terms of vibration acceleration time-history curves,vibration acceleration spectra,one-third octave spectra,and frequency vibration rates are also discussed.The findings show that the Qingdao Metro’s vibration response is greater than that of Shanghai Metro;the frequency vibration level of Qingdao Metro has surpassed China’s environmental vibration standard,whereas Shanghai Metro’s frequency vibration level is equal to environmental vibration standard.
