Abstract
The software and hardware tools for the instrumental estimation and control of the geomechanical state of engineering structures are presented. A description of the proposed technique for measuring radial and longitudinal displacements of check borehole contour is given. A research methodology and interpretation of experimental data with analysis and control of the stress-strain state of engineering structures are proposed. The results of testing the developed software and hardware in the conditions of industrial enterprises are presented.
