This is an open access article under the CC BY-NC-ND license (https://creativecommons.org/licenses/by-nc-nd/4.0) Peer-review under responsibility of the IRAS 2023 organizers Abstract Safe operation of building structures in areas of technogenic impact is an urgent and science-intensive problem. This problem is particularly acute in the areas of mining, both open and closed method. Mining zones affect the territories of entire cities, not to mention the sites of point development. As a result of the development of mineral deposits, such as potassium salts, a heterogeneous deformation field develops in the overlying layers of the soil mass, which significantly affects the deformation safety of building structures. This research is devoted to a part of boundary problems of the whole direction, the development of which should allow safe operation of structures, fallen into zones of technogenic impact. Here should be referred the problems of evaluation and correction of modern methods of analysis of limit deformations of soil mass in the vicinity of foundations of various building structures. It also includes the development of methods and approaches to estimate the deformation safety of the building structures themselves in terms of reaching the limit states. Approaches to solving the above problems are proposed in this paper. New results of numerical modeling of failure processes of reinforced concrete elements of structures experiencing a man-made impact as a consequence of deformation development near foundations of structures are presented. © 2023 The Authors.
