Abstract (EN): In the present paper a numerical procedure is presented in order to allow an efficient simulation of the vibrations induced by traffic from the source to the receiver ( building). The numerical model is divided into three distinct parts, comprising the simulation of rolling stock, the simulation of the tunnel-ground system and the simulation of the building. The solution is obtained by a compliance formulation between the three sub-systems, developed in the frequency domain. Regarding the simulation of the tunnel-ground system, which deals with unbounded domain problem, an efficient solution is developed using a 2. 5D technique based on the finite elements method, and adopting perfect matched layers ( PML's) for the treatment of the boundaries due to the truncation of the; finite elements mesh. On the other hand, the rolling stock is modeled using a multi-body approach, being the building simulated by a traditional 3D finite element approach.
