The test-measuring complex was created to study deformation and strength properties of rock samples with joints under direct shear conditions, under two types of boundary conditions: constant normal load (CNL) and constant normal stiffness (CNS). The updated version of the International Society for Rock Mechanics (ISRM) ASTM D 5607-08 standard was taken as the basis of the laboratory method for determining the shear strength of rock joints. Tests were performed on samples with joints from artificial geomaterial ? ...
