Cet article présente une étude menée sur un matériau gonflant compacté dans la gamme des succions comprises entre 8,5 et 287,9 MPa. Deux séries d'essais œdométriques à succion contrôlée sont présentées. La première permet la caractérisation de l'évolution de la compressibilité avec la succion. Elle montre que la pression de préconsolidation apparente et la pente de compression plastique sont significativement influencées par la succion. La deuxième série étudie l'influence de sollicitations hydromécaniques complexes sur la compressibilité du matériau qui apparaı̂t très dépendante du chemin hydromécanique.
This paper presents a study performed on a compacted swelling material in the range of suctions comprised between 8.5 and 287.9 MPa. Two series of tests were carried out with suction controlled oedometers. The aim of the first series was to study the compressibility as a function of suction. It showed that the apparent preconsolidation pressure and the plastic compression line are greatly affected by the applied suctions. The other series of tests highlighted the influence of complex hydromechanical paths on the compressibility of the studied material that appeared to be greatly influenced by the stress path followed.
