ProjectSOLUCIONES INNOVADORAS PARA EL AISLAMIENTO DE EDIFICIOS A LAS VIBRACIONES PRODUCIDAS POR INFRAESTRUCTURAS FERROVIARIAS SOTERRADAS (MINECO-TRA2014-52718-R)
Abstract
This work is focused on the analysis of noise and vibration generated in underground railway tunnels due to train traffic. Specifically, an analysis of noise and vibration generated by train passage in an underground simple tunnel in a homogeneous full-space is presented. In this methodology, a two-and-a-half-dimensional coupled finite element and boundary element method (2.5D FEM-BEM) is used to model soil–structure interaction problems. The noise analysis inside the tunnel is performed using a 2.5D acoustic BEM considering a weak coupling. The method of fundamental solutions (MFS) is used to validate the acoustic BEM methodology. The influence of fastener stiffness on vibration and noise characteristic inside a simple tunnel is investigated.
