AMBIENT VIBRATION INDUCED BY SPATIAL COUPLING VIBRATION OF VEHICLE-TRACK-BRIDGE SYSTEM

摘要：

In this paper,a model for spatial coupling vibration of vehicle-ballastless track-bridge system is established firstly,the reactions at bottom of bridge piers are obtained by random vibration analysis. A three-dimension finite element model of soil-building is established. The reactions at bottom of bridge piers are taken as the excitation of the threedimensional model of soil-building system. Through numerical analysis,it shows that the vibration of soil reduces as the distance increases; the vibration of building reduces with the distance increasing too,and the difference of horizontal and vertical vibration of building is little at lower layers but obvious at higher layers.
