Abstract

The isolation of surface structures from vibrations propagating through the soil is commonly achieved by various types of barriers placed into the ground between a source of vibrations and the affected structure. A different approach is to create an artificially layered soil by means of a stiff block embedded into the soil. Results obtained by experimental investigations and Boundary Element analysis are presented. Small scale experiments were performed in a specially designed soil container equipped with holographic wave measuring facility and conventional transducers. Surface model footings served as a source of propagating vibrations and as the model of a structure to be protected. The basic geometrical and physical parameters of the experiments were repro- duced in the BEM analysis. The results
