Prediction of Vibration Induced by High-Speed Train: Consideration of Soil Spatial Variability

The passage of high-speed train may cause substantial vibration to the adjacent buildings. Accurate prediction of the train-induced vibration is crucial to the mitigation of such hazard. The objective of this paper is to assess the impact of spatial variability of soil properties on the train-induced vibration. First, a three-dimensional finite difference model will be construct to solve the wave propagation equation induced by the passage of high-speed train. Then, the random field model will be used to model the spatial variability of the soil properties. By substituting the soil properties generated from the random field model to the finite difference model repeatedly, the impact of spatial variability on the displacement, velocity, and acceleration of the ground at different distances will be systematically studied. The results from this study will provide insights on how to mitigate the vibration hazard from a reliability point of view considering the uncertainties in the soil properties.
