TRIAXIAL CONTAINER TEST CELL ON A ROCK SAMPLE AND TEST METHOD USING SUCH A CELL

摘要

The present invention relates to a cell for triaxial stress tests on a rock sample, comprising a central body 1 in which a membrane 5 is placed enclosing said sample and exerting lateral stresses on said sample, as well as a means vertical pressure 6 acting on a section of the sample, said cell further comprising means for measuring deformation 10, 11, 12 of the sample related to the stresses applied to it. / P P The membrane 5 has a central longitudinal opening in which the sample 2 is introduced, a lateral outer surface coming into contact with the body 1 of the cell and a hollow interior volume 7 constituting a confinement chamber by a fluid introduced through an orifice 15 / P P Application to rock mechanics. / P
