Strength investigations of foundation of allocation of main structures of Pskem hydropower station on Pskem river

This paper presents the results of geomechanical studies of the siltstone massif experimental carried out in the right-bank adit at the site of the Pskem HPP dam. Primary shear experiments were carried out at 6 normal pressures on the stamp σ: 0.5 MPa; 1.0 MPa; 1.5 MPa; 2.0 MPa, 2.5 MPa, and 3.0 MPa
