INTERNATIONAL SOCIETY FOR SOIL MECHANICS AND GEOTECHNICAL ENGINEERING

Résumé

For the last two decades, researchers have focused on vibration isolation since these vibrations have a major impact on the comfort of building occupants located near the source. A usual assumption for the study of ground-borne vibration is considering soil as homogeneous, which is not realistic. Therefore, it is necessary to find the effect of layering of the soil on the efficiency of the geofoam-filled trench. This study presents the performance of geofoam-filled trenches in mitigating ground vibration transmissions by the means of a comprehensive parametric study. Fully automated numerical models are applied to evaluate the screening effectiveness of the trenches in the near and far field schemes. The parametric study is based on complete automation of the model through coupling finite element analysis software (Plaxis) and Python programming language to control input, change the parameters, as well as to produce output and calculate the efficiency of the barrier. The result of interaction between all governing parameters demonstrated that the depth (D) and shear wave velocity of the soil (Vs) are the most important parameters.
