摘　　要：磁悬浮列车是一种新型的交通运输工具,但目前关于磁悬浮运行时所产生的地面振动和其对周围环境的影响还未见报道。首次对这一问题进行了系统的现场测试,分析了磁悬浮列车产生的振动特性。与其它交通工具产生的地面振动比较,结果表明,磁悬浮运行时产生的地面振动远小于一般轮轨运输工具产生的地面振动;并且当列车运行速度达到较高值时也不会像高速铁路那样出现地面振动急剧增大的现象。Magnetic-levitating train is a new type of traffic means. The first commercial magnetic-levitation line in the world has been built in Pu Dong of Shanghai, China. However, there is no study about ground vibration induced by magnetic-levitating train and its influence on environment. In this paper, a large-scale and systemic field experiment about this problem is reported, and some helpful conclusions are drawn. The result of experiment indicates that the ground vibration by magnetic-levitating train moving is far less than that by wheel-track train, and the dramatic increase of ground vibration,which will happen when the wheel-track train run fast enough, is not found for magnetic-levitating train. The research in this paper will be helpful for magnetic-levitating train popularizing and protecting environment around the traffic line. [
