TRIAXIAL CELL FOR THE TESTING OF GEOMATERIALS IN COMPRESSION AND IN SHEAR

摘要

The invention relates to a cell (1) for testing geomateiias 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.
