TL;DR: In this article, a numerical model is presented to predict vibrations in the free field from excitation due to metro trains in tunnels, where the three-dimensional dynamic tunnel-soil interaction problem is solved with a subdomain formulation, using a finite element formulation for the tunnel and a boundary element method for the soil.

TL;DR: In this paper, a solution strategy is presented that allows for the evaluation of the second-order statistics of the response due to dynamic excitation based on the power spectral density function of the track unevenness.

TL;DR: In this paper, a general and fully three dimensional multi-body-finite element-boundary element model, formulated in the time domain to predict vibrations due to train passage at the vehicle, the track and the free field, is presented.

TL;DR: In this article, the effect of railway vibrations on passenger comfort and track performance is evaluated and the most suitable mathematical and numerical modelling strategies for railway vibration simulation, along with mitigation strategies are discussed.

TL;DR: In this paper, the authors present comprehensive experimental results on track vibration and soil response of a ballastless high-speed railway from a full-scale model testing with simulated train moving loads at various speeds.

TL;DR: In this article, the pipe-in-pipe model is used to model tangential forces at the tunnel wall and three different arrangements of supports are considered for floating-slab tracks.
