ABSTRACT

Very loose sand is defined as sand whose state is significantly looser than its critical state. In fact, the detailed stress –strain behavior of very loose sands have received almost no attention in the geotechnical literature. So, this paper is intended as a step towards the study of the behavior of very loose sands. In order to study experimentally the behavior of dry and wet loose sand on oedometric path under low stresses and with high values of voids ratio, we have realized several oedometer tests on different types of sand (such as : Hostun sand RF, sand 70-270 and Ziani sand), for which we have used different water contents. As a result of this work, several values of the characteristics of materials studied have been obtained and which permit to make some observations and conclusions concerning the behavior of loose sand.
