Grebenyuk S. Rationale for technology recovery and increase resilience buried and underground structures in areas of intensive filtering.

The thesis is devoted to solving the actual scientific problem - the justification of resource recovery technologies and raising the stability of buried and underground structures in areas of intensive filtering. The object of research - geomechanical and filtration-diffusion processes in the system "geological medium - concrete shell ground and underground facilities". The purpose of the research - based on the study of diffusion-geomechanical and filtration processes in the "concrete shell structures - the geological medium" to justify the resource-saving technology to restore and improve the stability of underground structures and buried surface of fuel and energy complex enterprises in the zones of intensive filtering. Research methods: analysis and synthesis of existing developments, theoretical studies of methods of mathematical modeling, laboratory and full-scale experiments. Basic scientific results: the factors that reduce the stability of the structures, the basic spatial and temporal patterns of diffusion-filtration and geomechanical processes in the concrete shell and the surrounding geological environment, leading to the destruction of the shell and the formation of voids outside the adhesive characteristics of the "shell-geocomposite" system were obtained, executed adaptation of tools and techniques for diagnostic facilities. The practical significance of the thesis is to develop and justify the parameters of resource recovery technologies and enhance the stability of structures. The results introduced in the energy sector and form the basis of two industry-standard technical documents.
