摘要
The present invention provides a cell for the triaxial stress testing of a rock sample, comprising a central body in which is placed a membrane enclosing said sample and exerting lateral stresses thereon, as well as a vertical pressure means acting on a section of the sample, said cell further comprising means for measuring the deformations of the sample related to the stresses which are applied thereto. The membrane has a central lateral opening in which the sample is introduced, a lateral external surface coming into contact with the body of the cell and a hollow internal volume forming a chamber providing confinement by means of a fluid introduced through an orifice.
