The rock mechanics laboratory is equipped with research equipment for carrying out strength and deformability tests of natural and artificial engineering materials with emphasis on specialised rocks tests. All tests were performed in accordance with standards and international guidelines that cover different areas of geomechanical investigations of rocks and soils. It is one of the few laboratories where researches of strength and deformability properties of rocks are carried out at high mechanical stresses using the triaxial cell, which enables confining pressures up to 150 bars.

Purpose of equipment:

  • The edometrov system allows you to specify the parameters of compressibility of soil. The edometer cell is designed so that the pattern of the lower and the upper side surrounded by the porous plates allows the passage of water during the test. The cells are connected to the burette system, which allows the determination of the coefficient of water permeability of soil at different load levels that the sample is exposed to during the test.
