Abstract

This paper discusses a detailed investigation to determine the microcrack closure and opening of a homogeneous isotropic sandstone during four different triaxial tests: undrained deviator triaxial test; undrained triaxial test with constantly increasing stress; drained triaxial test connected with decreasing confining pressure and drained triaxial test with constantly increasing stress. An analysis of the results is presented. | Cet article présente une analyse détaillée des processus de fermeture et ouverture de microfissures dans un grès homogène et isotrope soumis à quatre sollicitations mécaniques différentes à l'appareil triaxial: essai triaxial non drainé sous déviateur croissant; essai triaxial non drainé sous chemin de contraintes croissantes contrôlées; essai triaxial drainé sous pression de confinement décroissante; essai triaxial drainé sous chemin de contraintes croissantes contrôlées. Les résultats de ces essais sont analysés.
