Title: Study on Ambient Vibration Induced by Spatial Coupling Vibration of Vehicle-Track-Bridge System and Isolating Measures
Abstract:Building vibration is induced by spatial coupling vibration of building foundation transferred from vehicle-track-bridge system of urban rail transportation through ambient soil.Aiming at this problem...Building vibration is induced by spatial coupling vibration of building foundation transferred from vehicle-track-bridge system of urban rail transportation through ambient soil.Aiming at this problem,a model for spatial coupled vibration of vehicle-sludgeless-track-bridge system is established in this paper,and then the reactions at bottom of bridge piers are obtained by random vibration analysis.A three-dimension finite element model of soil-building is afterward established,the vibration of ambient soil and surrounding building are numerically analyzed.And vibration isolation trench is added to the model,the effect of vibration isolation is analyzed numerically,it shows that the vibration isolation effect is significant.Read More
