Ecological protection and friendly environment have become the important aspects of current socio -economic life. On the basis of the reality that the subway or inter-city train vibration impacts on the surrounding environment and taking the track-tunnel as vibration structure into train computing model, the train-tunnel coupling system model is established while considering coupling function between train and tunnel system. Based on this, the vibration as well as its impact methods and evaluation indicators toward the surrounding environment is discussed and analyzed. And the vibration effect caused by train vibration is analyzed and evaluated according to the depth of the building, tunnel track type,train speed,axle load and other parameters,providing basis for damping and dealing measures for the subsequent works.%结合地铁或城际列车振动对周边环境影响的现实,将轨道-隧道作为参振子结构纳入车辆计算模型,考虑车-隧体系耦合动力作用,建立了车-隧耦合动力分析模型.在此基础上,讨论分析了振动及对周边环境的影响方式和评估指标,并根据建筑物埋深、隧道轨道类型、列车速度、轴重等参数,分析评估了列车振动对周边的振动影响,可为后续工程减振对策及处置措施提供依据.
