CA 2730046
The invention relates to a cell (1) for testing geomaterials on cylindrical specimens (2), of rock, ground or materials manufactured on sampling sites, comprising at least one piston (4, 5) for subjecting a specimen to a stress directed along the longitudinal axis of the specimen (2). According to the invention, the cell has, in addition, means (7) for shearing the specimen, capable of cracking the specimen while it is being compressed in said at least one piston.
L'invention est relative à une cellule (1) d'essai de géomatériaux sur des échantillons (2) cylindriques, de roches, de sols ou des matériaux fabriqués sur des sites de prélèvement, comprenant au moins un piston (4, 5) pour soumettre un échantillon à une contrainte dirigée selon l'axe longitudinal de l'échantillon (2). Selon l'invention, la cellule présente, en outre, des moyens (7) de cisaillement de l'échantillon aptes à permettre la fissuration de l'échantillon lors de la compression de l'échantillon dans ledit au moins un piston.
