Annotation:
By now, the vast majority of domestic laboratories, where core material is studied in order to determine the strength characteristics under conditions of comprehensive compression, use the methods that involve pseudo-triaxial loading. The main disadvantage of this method is the fact that the introduced assumption of equivalent horizontal stresses most often does not correspond to reality. The paper describes the results of kinematic scheme simulation, allowing to provide independent triaxial loading of the core, thereby creating true reservoir conditions.
