摘　　要：针对地铁列车运行所诱发的高频次振动对高架桥及周边环境产生的影响,通过室内试验、现场监测和数值模拟获取地铁列车运行过程中的振动信息,构建不同结构形态的隧道模型,揭示地铁列车运行过程中振动波在高架桥及周边环境的传播规律。With the continuous expansion of urban subway network,the constant improvement of the speed of subway trains and people’s requirements for living quality,the high-frequency vibration induced by the operation of subway trains has a certain impact on the viaduct and the surrounding environment of urban residents. Therefore,the study use different structural forms of tunnel models to reveal the propagation law of vibration waves in the viaduct and surrounding environment during the subway operation with the vibration information obtained by means of laboratory tests,on-site monitoring and numerical simulation.
