TL;DR: In this article, an analytical three-dimensional model for the dynamics of a deep underground railway tunnel of circular cross-section is presented, where the tunnel is conceptualised as an infinitely long, thin cylindrical shell surrounded by soil of infinite radial extent.

TL;DR: In this paper, a track model was added to a previously developed three-dimensional tunnel model in order to assess the effectiveness of floating-slab track, where a concrete slab supporting the two rails was mounted on rubber bearings or steel springs to isolate it from the tunnel invert.

TL;DR: In this article, the free-free dynamics of three small-scale vibration isolator models (two single-stage isolators and one two-stage isolateator) are discussed.

TL;DR: Reading this tutorial is expected to get a flavour of what moving-load problems are about, what general methods are available and what research has been done from studying this tutorial.

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 article, an analytical three-dimensional model for the dynamics of a deep underground railway tunnel of circular cross-section is presented, where the tunnel is conceptualised as an infinitely long, thin cylindrical shell surrounded by soil of infinite radial extent.

TL;DR: In this paper, a 2.5D coupled finite element-boundary element methodology for the computation of the dynamic interaction between a layered soil and structures with a longitudinally invariant geometry, such as railway tracks, roads, tunnels, dams, and pipelines is presented.

TL;DR: In this article, a 2.5D boundary integral equation is used for the analysis of ground vibrations induced by railway traffic, where the finite element method is combined with a boundary element method.
