A 2.5D finite element and boundary element model for the ground vibration from trains in tunnels and validation using measurement data
TL;DR: In this paper, a numerical model for ground-borne vibration produced by trains running in tunnels is presented based on the assumption that the geometry and material properties are invariant in the axial direction.

An efficient approach for prediction of subway train-induced ground vibrations considering random track unevenness
TL;DR: In this paper, an efficient and robust approach is presented for the prediction of subway train-induced ground vibrations considering random track unevenness. And the influence of the train speed on the ground vibrations is also investigated, in which two types of track structure, namely the direct fixation track and floating slab track, are considered.

Finite-element analysis of seepage in elastic media
TL;DR: In this article, a variational principle is used in conjunction with the finite element method to solve the initial boundary value problem of flow in a saturated porous elastic medium, which results in a powerful solution technique for the determination of stress and displacement history, both for the solid and the liquid phases, for arbitrary boundary conditions and within complex geometrical configurations.

Prediction of ground vibration from trains using the wavenumber finite and boundary element methods
TL;DR: In this paper, the authors use the wavenumber finite/boundary element (WBE) model to model ground and built structures, such as tunnels and tracks, and apply it to surface vibration and tunnel vibration analyses.

A 2.5D finite/infinite element approach for modelling visco-elastic bodies subjected to moving loads
Yeong-Bin Yang,Hsiao-Hui Hung +1 more
TL;DR: In this paper, a 2.5D finite/infinite element procedure for dealing with ground vibrations induced by moving loads is proposed, where the profile of the half-space is divided into a near field and a semi-infinite far field, and the near field containing loads and irregular structures is simulated by finite elements, while the far field covering the soils extending to infinity by the infinite elements with due account taken of the radiation effects for moving loads.
