Abstract
The building vibration induced by train loads has aroused people’s great attention. Many investigations have been carried out by many researches in order to evaluate the effect of train-induced vibration on environment. But they have not shown the reason why enlarged vibration region exist in front of a building. In this paper, building structure vibration induced by train loads was analyzed by numerical simulation method performed by ANSYS. Based on numerical results, it’s concluded that the reason for this phenomenon that enlarged vibration region may exist in front of a building is the result that incident wave and the reflected wave superpose mutually. Subsequently, the influence of barrier depth on the enlarged vibration region is also discussed.
