摘　　要：轨道交通运行引起的环境振动问题,已成为土木工程界关注的一个新的课题。对南京市栖霞镇某场地进行了列车振动现场试验,得到了不同列车车型与车速下的地面振动速度时程曲线,给出了地面振动速度的频谱特性和衰减规律,分析了列车运行引起的环境振动的传递路径,为进一步研究轨道交通振动控制提供了参考。　The problem of the environmental vibration induced by rail transit has been a new subject in the area of civil engineering.Based on the field test that runs at Qixia town,in Nanjing city,the time histories of the ground vibration due to different types and velocities of the train are obtained in this paper.The frequency character and attenuation of ground surface velocities are also generalized.The transfer path of the traininduced environmental vibration waves is analyzed to give reference to the further research of the control of rail transit vibration.
