• W2014282701 abstract "Within the framework of an extended elastoplastic constitutive model for unsaturated soils (loading-collapse (LC) model), an experimental programme was performed in an osmotically controlled suction triaxial apparatus. The laboratory behaviour of a statically compacted silt was studied, and particular attention was given to the volume changes monitored during shear. Isotropic loading tests confirmed the main features of the LC model related to the effect of suction on volume changes, and allowed a direct determination of the LC curve. Constant σ 3 and a few constant q shear tests were performed in order to study yielding and plastic flow at various increasing suctions, starting from the as-compacted condition. Several yield criteria were considered, depending on the type of test performed. Some similarities between compacted unsaturated soils and natural soft soils were shown, such as the inclined elliptical form of the yield curve, which results from the anisotropic state of stress prevailing during k 0 compaction. Some preconsolidation effects due to increasing suction were identified, and an approximately isotropic suction hardening phenomenon was evidenced, together with a non-associated flow rule. The direction of the plastic strain increment seemed almost independent of the suction, and a hyperbolic plastic potential, similar to that of sand, was found satisfactory. Inclined ellipses were chosen for modelling the yield curves. As for any simple elasto-plastic Cam clay type model applied to overconsolidated soils, the predicted stress—strain curves showed a sudden transition at yield, whereas a much more gradual transition was observed in practice. Volume change prediction appeared satisfactory, showing the validity of the hyperbolic plastic potential. Un programme expérimental, mené à Paide d'un appareil triaxial à succion contrôlée par un dispositif osmotique, a été é1aboré dans un contexte élasto-plastique développé pour les sole non saturés (modèle LC). On a étudié au laboratoire le comportement mécanique d'un limon compacté statiquement, en accordant une importance particulière à la mesure des variations volumiques se produisant pendant le cisaillement. Des essais de compression isotropes ont confirmé les aspects essentiels du modèle LC qui traitent des effets de la succion sur les variations de volume, et ont permis la détermination de la courbe LC. Des essais de cisaillement triaxial à σ 3 constant, et quelques tests à constant ont été réalisés pour étudier la plastification et l'écoulement plastique du matériau à différentes succions, égales on supérieures à la succion de compactage. On a considéré, suivant le type d'essai réalisé, divers critères de plastification. Un certain nombre d'analogies avec les propriétés des sols mous naturels ont été mises en évidence sur les sols compactés non saturés: la forme de la surface de charge est elliptique inclinée, du fait de Panisotropie de état de contrainte appliqué pendant le compactage. Des effets de préconsolidation dus à une succion croissante ont été identifiés, ainsi qu'un écrouissage en succion isotrope et une regle d'écoulement non associée. La direction de l'incrément de déformation plastique s'est ré vélée têtre indépendante de la succion. Comme dans les sables, un potentiel plastique hyperbolique est apparu satisfaisant. On a modélisé les surfaces de charge par des ellipses inclinées. Comme dans les modàles Camclay classiques, les courbes effort-déformation calculées avec le modàle présentent une transition marquée à la plastification, alors que cc passage est progressif dans la réalité Les changements de volume calculés sont apparus satisfaisants, ce qui confirme la validité du potentiel plastique hyperbolique." @default.
