Abstract (EN): In the present paper a numerical study is presented in order to evaluate the efficiency of different countermeasures that can be adopted to mitigate vibrations inside buildings due to railway traffic in tunnels. The numerical model is substructured and is composed by three autonomous modules to simulate the main parts of the problem: i) generation of vibrations (train-track interaction); ii) propagation of vibrations (track-tunnel-ground system); iii) reception of vibrations (building coupled to the ground). A comparative analysis is carried out on the potential benefits of improving the geometrical quality of the track and of the installation of resilient elements under the railway slab, being evaluated the vibrations inside of a building due to railway traffic in a shallow tunnel located in Madrid. Finally, some considerations are made regarding an engineering solution that could involve the combination of several types of mitigation measures, taking advantage of the potentialities of the model. © 2018 Taylor & Francis Group, London, UK.
