TL;DR: In this paper, a 2.5D coupled finite element and boundary element method was used to model soil-structure interaction problems in underground railway tunnels. And the influence of fastener stiffness on vibration and noise characteristic inside a simple tunnel was investigated.

TL;DR: The present methodology has been specifically designed to be used in general assessment studies about ground-borne underground railway-induced vibrations where decisions on the type of track and/or the application of mitigation measures at the source, as soft rail-pads, under-ballast or under-slab mats, have to be made.

TL;DR: In this paper, a new prediction methodology for longitudinally invariant soil-structure interaction problems in elastodynamics is proposed, which uses the finite-element method to model the structure, the boundary element method as a model of the wave propagation through the soil, and the method of fundamental solutions as a post-processing tool to compute the response of the soil.

TL;DR: A comprehensive numerical approach formulated in the two-and-a-half dimensional domain (2.5D) for modelling track/tunnel/soil systems in the context of ground-borne railway-induced vibration problems considering a full-space model of the soil is proposed.

TL;DR: In this article, the authors present a methodology for the design of vibration abatement solutions to be applied in railway tunnels in the context of problems where an already operative underground railway infrastructure is inducing excessive vibration levels to particular nearby buildings.
