After stabilization of the vertical displacements under load: ke P, the uniform torque is applied to the ring stamp in the contact plane, as a result of which the die rotates around its central axis. Then, the angle of its rotation f in the contact plane is measured, the maximum torque M / 1 is measured, the drive: to the die's chipping along the cut plane, and using it the maximum value of the tangential stress is determined by a constant value of torque x stamp on the destroyed surface M and on the line, the value of the tangential stress C Qg .... When the ratio of the internal diameter of the ring stamp to the outer one is more than 0, 5 the distribution of tangential 2 is determined by the magnitude of the torque, and normal stresses G,limited by the magnitude of the vertical load, along the cut-off plane at the base, the punch can be taken uniformly. The same tests are carried out, resulting in the determination of: 2 "s Based on the data obtained, the dependences tr f (Q), which determine contact strength parameters. Using the linear portions of the dependence 5 (P) and f f (M), determine the modulus of the general DB deformation, the shear modulus GO, and the Poisson coefficient Oo. The proposed method for determining the deformability of massive media and the strength of their contact with concrete has the following advantages over the known: as a result -. days of one experience determine all the main characteristics of deformed rock that has a different base
