ABSTRACT
This paper presents wetting induced (or collapse) deformation of an undisturbed sandy soil from Brazil. In this investigation, the main testing program has been performed using oedometric tests especially designed to apply and control the suction through axis-translation technique. Two types of test have been carried out: tests in which a combination of loading paths at constant suction were applied; collapse tests under constant loading in order to determine the collapse potential during wetting. Also, the effect of wetting-drying cycle on the collapse behavior was studied.
