Abstract

This paper presents a model about using a concrete wave barrier for mitigation of ground vibrations induced by a high-speed train. The paper considers a numerical model which was divided into two parts. In the first part, time dependent reaction of a recorded point during train movement was modeled. The model included concentrated moving loads at constant velocity on an elastic beam with spring supports. In the second part, the results of the first part were applied as input data of loading. The aim of this paper was to evaluate the dynamic behavior of a subsoil layer during wave propagation before and after constructing a wave barrier. The wave barrier mitigated 12 to 17 percent of the vibrations in the distance of 30m to 40m in the upper part of the subsoil respectively. This indicated that the wave barrier reflected and also absorbed some component of waves. The mitigated maximum total velocities fulfilled the accepted level of vibration.
