CRITICAL ANALYSIS OF APPROACHES TO DETERMINING THE STRESS-STRAIN STATE OF THE "HORIZONTAL WORKING – LAYERED MASSIF" SYSTEM

Purpose. To perform a critical analysis of approaches to determining the stress-strain state "horizontal working – layered massif" system. Obtain informed decisions for applying specific approach case massif. substantiate metric finite element models system massif". Methodology. achieve purpose, peculiarities rock were analyzed. It has been proven that layering is most important structural feature surrounding A detailed mathematical methods solving elastic-plastic problems massifs was performed. Findings. During problem massif", two identified, each which its own set methods. These are analytical one and numerical, them special features. confirmed recently studies - mostly based on numerical approach, leaving only small share total volume one. determined introduction methods, in particular, method elements specialized software complexes, allowed change concept research geomechanics mechanics underground structures, shifting focus simulation modeling. Originality. Based results approaches, use finite-element scientifically substantiated. this allows be taken into account without additional assumptions. Practical value. In course research, it spatial model from flat prototype, but limited thickness 0.1 or 1 m, adequate given task, provided plane deformation considered.
