［摘要］为了分析地铁运行诱发沿线建筑物振动的特点和传播规律，评价地铁采取更换弹性轨道扣件对降低建筑物振动的影响，验证基于理论分析得出的地铁运行引起建筑物振动的特点的正确性，需要用到相关振动的实测数据，而目前此方面有价值的可用实测数据却相对匮乏，这无疑阻碍了对城市轨道交通系统运行引起的周围建筑物振动影响的研究。对受上海地铁某线路影响较为严重的一座住宅进行了长时间、大规模的现场实测，采集了大量的振动数据。通过对实测数据的统计分析，获得了地铁运行诱发沿线建筑物振动的特点和规律，总结了建筑物内竖向振动传递规律，检验了Vanguard（先锋）型轨道扣件的减振效果。

Abstract: For the purpose of analyzing the feature and law of the building vibration caused by the subway, appraising the vibration reduction effect of elastic rail fastener, checking the correctness of the feature of building vibration based on theoretical analysis, the measurement of vibration is desperately needed. Currently, the available data of the vibration is rare, which hampered the study of the building vibration induced by the subway. A large-scale and long-time site measurement on a building which was greatly influenced by a subway tunnel in Shanghai was conducted. A great number of vibration data was thus obtained. The characteristic and law of the subway-induced building vibration were summarized, the vertical vibration propagation characteristic in buildings was gained and the vibration reduction effect of elastic rail fastener was testified by analyzing the vibration data.

Keywords: subway-induced vibration; vibration characteristic; elastic rail fastener; site measurement
