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.
Résumé
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.
