Surface vibrations caused by human activities such as industrial activities, plying of high-speed traffic(e.g. on highways and
railways), piling and blasting during construction and demolition works usually reach limits where they have become problematic for people and buildings. Very often, it even reaches dangerous limits where they are no longer safe for human life. So many solutions have devised to mitigate the effects of vibration, and one of them is vibration screening by the construction of trench wave barriers. This paper has focused on evaluating the screening efficiency of in-filled materials and the impact of different parameters of trench wave barriers on efficiency. This paper has presented a numerical study and subsequent validation, a 3D finite element study of vibration screening in PLAXIS-3D against stationary surface vibrations using a trench wave barrier filled with an elastic, isotropic, homogeneous half-space. Key parameters have determined and studied thereof. The results of the numerical and experimental study have found in close agreement
