Abstract
Technogenic impact on the geological environment inevitably leads to a change in the properties of rocks. Engineering structures quite often directly interact with rocks, therefore, reliable determination of their properties is an urgent task in construction. From a practical point of view, knowledge of not only the physical and mechanical properties of rocks, but also their characteristics in contact with technogenic impact is of great interest. This determines the relevance of studying the characteristics of changes in the properties of rocks under the influence of technogenic factors. The aim of the work is to consider the issues of changing the properties of rocks under the influence of technogenic factors of the geological environment. Technogenic impact on the geological environment is classified according to various criteria, and is divided into global, zonal, regional and local categories. The authors rightly give preference to the following operating factors: pressure, fluctuations in the stress state, hydrogeological conditions, changes in the composition of groundwater, etc. Particular attention is paid to rock swelling, rock salinization and the influence of various microorganisms on rocks. In the article of the above authors, it is proposed to consider in detail the orohydrographic conditions of the studied geological environment, geomorphological conditions of the territory, geological structure, hydrogeological conditions (upstream, groundwater, interstratal waters), geo-dynamic conditions (all processes and phenomena expressed in a given territory), as well as to study the composition (mineral, granulometric, chemical), the state of rocks (moisture, density, porosity) and properties of rocks (strength, deformation and geological) - for a comprehensive assessment of the surrounding geological environment. Attention is also paid to the dynamic impact, i. e. the factors of liquefaction, thixotropy and other soil deformations are given.
