Abstract
The influence of dangerous geological and man-made processes on the real geological environment leads to scattered destruction, which in turn causes the degradation of deformation properties, the reduction of effective elastic properties, and the change in the structure of the fracture-pore space and, accordingly, the change in filtration properties and pore pressure. A characteristic feature of the mechanical behavior of the geological environment is the possibility of accumulating mechanical damage even under small quasi-static loads, not only under the action of shear stresses, but also under tension and compression. The generation of cracks is inevitably accompanied by the absorption of energy owing to the growth of cracks and the corresponding change in the structure of the geological environment in the vicinity of crack banks. Military operations are a source of man-made cracks. Consequently, a significant number of hydro technical structures in Ukraine were damaged and destroyed. This makes it necessary to diagnose the stability of hydro technical structures. For this purpose, an appropriate automated system was developed. The adequacy of its results was verified through experiments using the acoustic emission method.
