Abstract
The invention relates to a triaxial cell for testing geomaterials on specimens. The triaxial cell has at least one piston for subjecting a specimen to stress directed along the longitudinal axis of the specimen. Hydraulic means are provided for subjecting the lateral wall of the specimen to a stress, under the pressure of a fluid. The cell has at least one sealed test chamber-in which the specimen is placed, and a circuit for the controlled pressurization of said test chamber with a fluid, called the pressurizing fluid, and for the controlled draining of said fluid therefrom. The cell has mechanisms for subjecting the specimen to a tensile force, which are configured for removably fastening it between two attachments intended to move apart or closer together under the action of the piston so as to subject said specimen to longitudinal stress or on the contrary to remove the load therefrom.
