Diagnostics and control of the hydro-technical construction state are the most important actions at the system of safety keeping with exploiting high-pressure dams. Considered in the paper stress-strain control system is attributed to special one in exploiting period. That system is non-traditional for hydro-technical constructions. It is aimed at specifying model calculations of stress-strain state of constructions, defining peculiarities of its deformation and can be used to enlarge the monitoring system at plac...

When operating waterworks, it is required to refine the data on actual stresses in different structural elements of the facilities. The authors put forward a nonconventional approach to expanding the waterworks observation network. The quantitative assessment of stresses in a structural element at the given moment of time is performed using borehole techniques of geomechanics. Later on, the change in the stresses and deformations is controlled based on the data on deformation of sidewalls and damage of galleries u...
