In most cases, most of the vibration energy source with the dynamic flux propagation Rayleigh waves propagated nearthe surface of the ground may cause movement of the ground and a high level of efforts that transmit vibrations fromunderground to the supported structures and adjacent structures. The permanent negative effects of these majorvibrations on foundations cause structural damage to adjacent buildings, especially those supported by deposits ofsoil/soft soil. This type of vibration can cause adverse effects in the nearby areas and inside buildings to sensitiveelectronic equipment and to devices/facilities measuring and alike can have a major impact on occupant comfort. Theliterature shows that the best assessing criterion is the maximum speed of oscillation of the particle soil - PPV (PeakParticle Velocity).The paper aims to present a case study on determining the effects of vibration levels generated by non-seismic sourceson structures. A criterion for assessing the vibration at internationally level is considered and also some existingsolutions in the literature to reduce the level of vibration are presented. The proposed systems were evaluated andcompared using particle displacements reductions obtained in soil through intensive study of parameters. All proposedfilled barrier systems performed well in order to reduce surface waves and effectiveness shielding, but in most cases avariable protection in the presence of structure was provided.
