Vibration and Noise Measurement of Railway Station Hall Induced by High-Speed Trains

  • 摘要: 为研究列车通行对综合交通枢纽振动噪声的影响,以成渝高铁沙坪坝站为工程背景,通过现场试验实测了站房候车厅、站台、轨道板的振动加速度以及候车厅、站台区域、轨行区的辐射声压. 通过对实测信号分别进行了时域分析和1/3倍频程分析,探究了列车作用下站房的振动传递规律及噪声辐射特性. 结果表明:在列车运行荷载作用下,站房与站台的结构振动优势频段为10.0~80.0 Hz,振动随振源距离的增大而减小,站台到候车厅总振级衰减最大值达到13.5 dB;轨道板峰值振动加速度级出现在400.0 Hz处,约为101.0 dB;对候车厅而言,噪声声压级的优势频段为20.0~2 500.0 Hz,列车进站总声压级比列车出站高0.5~1.3 dB(A);对站台而言,噪声的优势频段为125.0~1 000.0 Hz,列车出站总声压级为86.3 dB(A),比列车进站时高1.3 dB(A);对轮轨噪声自身,其优势频段为200.0~2 500.0 Hz,列车进站噪声总声压级为91.1 dB(A),较列车出站时高3.2 dB(A).
