  3. Abstract:
  4. Dynamic loads in many projects cause vibration in soil. The propagated energy has a destructive effect on the foundation of the adjacent structures. One of the suitable methods for preventing these harmful waves is active isolation. In this paper the mentioned phenomena is studied by conducting some physical model tests. The loose sandy models are excited by impact type load of a tamper and the response for models with and without trench are measured at different points. Two types of closed form or continuous trenches are used. In closed form trench models, the effect of trench on acceleration attenuation and the ratio of vertical to horizontal accelerations were investigated. In continuous trench models, the effect of trench depth on its efficiency was considered. It has been observed that getting farther from the trench, lower acceleration was measured. Furthermore, increase the trench depth will provide more efficient isolation. © 2006 Taylor & Francis Group
