An efficient numerical method is developed for the evaluation of the influence of the track structure on vibration and noise in a neighboring building induced by a subway train. In order to save computational cost, the three-dimensional track/tunnel/soil interaction problem is formulated by virtue of the Floquet transform and then reduced to a quasi-two-dimensional problem. Furthermore, the vibration and noise levels in a neighboring building are predicted using the numerical result and empirical evaluation methods. As examples, two types of tracks with under-sleeper pad and with under-slab sheet are considered. Through numerical analyses, the influence of track structures on the vibration and noise in a building is examined.
