ABSTRACT: Ground vibrations induced by machine foundations can cause unfavourable effects which can be minimized by installing a suitable wave barrier. A full scale field study has been conducted to investigate the protective performance of both open and in-filled GeoFoam wave barriers and to examine the influences of the geometry and location. Experimental results show that the proposed wave barriers can effectively scatter the generated surface steady state waves. The protective performance has been assessed numerically by developing a 2D FE model. The field investigations have been compared with those obtained numerically, interpreted and some guidelines regarding some key parameters are outlined.
RÉSUMÉ: vibrations du sol induites par des fondations machine peut provoquer des effets défavorables, qui peuvent être minimisés par l'installation d'une barrière d'onde appropriée. Une étude à grande échelle sur le terrain a été menée afin d'évaluer les performances de protection à la fois ouvert et rempli de barrières vague GeoFoam et d'examiner l'influence de la géométrie et l'emplacement. Les résultats expérimentaux montrent que les barrières d'onde proposée diffusant de façon efficace la surface des vagues générées état d'équilibre. La performance de protection a été évaluée numériquement par l'élaboration d'un modèle 2D FE. Les enquêtes sur le terrain ont été comparés avec ceux obtenus numériquement, interprété et des lignes directrices en ce qui concerne certains paramètres clés sont énoncés. 1 INTRODUCTION
