By the numerical stress–strain analysis using the method of boundary integral equations and the model of linearly deformable quasi-isotropic model of a layered rock mass has found the nature, mechanisms and specifics of stress state distribution in enclosing rock mass around the powerhouse hall and transformer room of the Rogunskaya Hydroelectric Plant. The influence of stage-wise face tunneling of the powerhouse hall on the elastic convergence between the bottom and roof of the hall as well as on the inelastic deformation of adjacent rock mass is assessed.
