The stability of the dam on Rogunskaya HPP made of ground materials is studied on the basis of numerical calculations of its spatial stress-strain state. The deformation and strength properties of the materials com-posing the dam body defined in the triaxial compression devices were used in the calculations. Limit values of strength properties of materials and controlled values of diagnostic indicators of a dam at which safety of its work is provided are established.
