Abstract

Investigation of mountainous rock destruction under different thermodynamic conditions<br>is one of the most important problems of the engineering hazard. It was earlier considered<br>that this destruction is taking place when at least one component of the stress tensor<br>reaches some critical value called as a material strength. However, conducted analysis<br>allowed us to conclude that such a notion is correct only for a relatively short-term action<br>and is unsuitable by a prolonged stress to target. On the basis of the detail theoretical<br>analysis we propose a new physico-mathematical conception describing the destruction<br>process as a phase transition. From this viewpoint, generation of microfault is an initiation<br>of a new phase. Such a generation causes emission of a definite number of seismo-acoustical<br>impulses. Quantity of the impulses during the time unit shows an intensity of process<br>destruction and frequency of oscillation indicates dimension of the microfaults forming.<br>Thus, the suggested conception allows to develop procedures for monitoring of durability<br>of different artificial underground constructions: mines, reservoirs and military objects as<br>well as other artificial and natural structures.
