摘　　要：为了研究某地铁运营引起TOD民宅建筑的振动和噪声情况,对列车通过引起轨道结构以及建筑物地下、地面振动及室内振动和噪声进行现场测试。结果表明:振动由钢轨传递到道床板,再传递到隧道壁的整个过程中不断衰减,其中钢轨振动以高频振动为主,隧道壁振动以低频振动为主;建筑物的地下振动和室内振动主要集中在50~100Hz的频带上,室内噪声主频带为50~100Hz;建筑物结构及地基传播50~100Hz振动的能力更强,推测结构二次噪声超标是由于振源的优势频率与振动传播路径中不利于振动衰减的频率重合导致建筑物室内振动响应较大所导致。In order to study the vibration and noise of TOD residential buildings caused by a subway operation,field tests were carried out on the vibration and noise of track structure,underground and ground of buildings and indoor vibration and noise caused by trains.The results show that the vibration decreases continuously during the whole process of transmission from rail to bed plate and then to tunnel wall.The rail vibration is mainly high frequency vibration,and the tunnel wall vibration is mainly low frequency vibration.The underground vibration and indoor vibration of buildings are mainly concentrated in the frequency band of 50~100Hz,and the main frequency band of indoor noise is 50~100Hz.The building structure and foundation have a stronger ability to propagate 50~100Hz vibration.It is speculated that the excessive secondary noise of the structure is caused by the coincidence of the dominant frequency of the vibration source and the frequency that is not conducive to vibration attenuation in the vibration propagation path,which leads to the larger indoor vibration response of the building.
