Abstract

This paper discusses results of experimental study. It highlights the influence of modes of reconstitution of samples on structural architecture of granular materials. Undrained triaxial tests were carried out on Hostun sand HN31. Different procedures for the preparation of the samples were used: moist tamping, dry pluviation and water pluviation. Bender elements which transmit and receive shearing waves have been use to study the structural anisotropy induced by each mode of deposition and its evolution during the loading path.Results obtained showed that the three different methods of preparation induce anisotropy of soil and lead to different mechanical behavior during the undrained shearing tests.
