Abstract
The intact rock mass stresses can be calculated in terms of stresses and displacements only with formulation of an additional problem. The intact rock mass stress state can be recovered using the experimental determination of opening of cracks lying at an angle to a horizontal line. The diagram of tensile stresses at an extension of a cut can be plotted using the tension diagram of a reference sample.
