［摘要］为了研究地铁车辆段试车线列车运行诱发上盖住宅的竖向和横向振动特点及传播规律，针对国内某地铁车辆段试车线上盖住宅进行了现场实测，获得了列车以不同车速运行时上盖住宅各层的竖向和横向振动实测数据，并分析了楼板振动在时域和频域内的振动特点及衰减规律，探讨了不同车速对上盖住宅楼板振动的影响规律。结果表明：当地铁车辆段试车线列车正常运行时，上盖住宅竖向振动明显大于横向振动，在上盖住宅5层出现最大振动响应，其竖向和横向分频振动加速度级峰值分别为75.71dB和56.04dB，对应频率均为40Hz；车致振动沿上盖住宅向上传播时，各楼层的竖向和横向振动随层高增大呈放大趋势，但在靠近顶层位置出现振动衰减，且竖向振动在低层的放大效应更明显；列车速度对上盖住宅的振动响应有较大影响，振动响应总体随列车速度增大呈放大趋势，但并非车速越大振动响应越大，建筑物各层楼板振动响应取决于不同车速下振动波的振源荷载特性和建筑物楼板本身的动力特性。

Abstract: In order to study the train-induced vertical and lateral vibration characteristics and propagation laws in over-track residence on the testing line of metro depot, field measurements were carried out in over-track residence on the testing line of a metro depot in China. The vertical and lateral vibration data of each floor in the over-track residence were obtained at different speeds of metro trains, and the vibration characteristics and attenuation law of each floor in over-track residence was investigated in the domains of time and frequency, the influence laws of the over-track residential vibration response at different speeds were discussed. The results show that the vertical vibration of the over-track residence is obviously greater than the lateral vibration when metro trains are running on the testing lines of metro depot, the maximum vibration response occurs on the fifth floor of the over-track residence, the peaking of vibration acceleration level at different frequency in vertical and lateral direction are 75.71dB and 56.04dB respectively, and the corresponding frequency are both 40Hz. When the train-induced vibration propagates upward along the over-track residence, the vertical and lateral vibration of each floor presents an amplification trend with the increase of the floor height, but the vibration attenuation appears near the top floor, and the amplification effect of vertical vibration is more obvious in the lower floor. The train speed has a great influence on the vibration response of the over-track residence, the general trend is amplification with the increase of train speed, however, it is not that the greater the speed, the greater the vibration response, the vibration response of each floor of the building is determined by the vibration source load characteristics and the dynamic characteristics of the building floor itself.
