Cell triaxial of geomaterials under pressure and shearing

摘要

The present invention relates to a cell (1) of the test of geomaterials on samples (2), of rocks, floor or of the materials produced on site, comprising at least one piston (4, 5) for subjecting a sample to a force directed along the longitudinal axis of the sample (2). According to the invention, the cell has, in addition, means (7) of the shearing of the sample to be able to allow the cracking of the sample during the compression of the sample in the said at least one piston.
