Abstract: The analysis of the results of computer geomechanical modeling in solving problems of underground, open and construction geotechnology is presented. The method of transition to three-dimensional digital models is substantiated. The features of setting the tasks of geomechanics of the soil foundations of structures are revealed. The aim of the work is to develop a methodology for volumetric modeling of the stress-strain state of the foundations of technical structures, which ensures an increase in the accuracy of the forecast, including when using technologies for managing soil properties. Geomechanical modeling of soil bases is based on the finite element method (FEM). With the help of FEM, it is possible to simulate most of the geomechanical processes that occur in soils and compare various criteria of limit states. After processing, the obtained data can be presented in numerical or graphical form. Calculations using FEM can take into account both linear and nonlinear forms of deformations, solve problems of inhomogeneous deformation of the medium with a linear elastic coupling of stresses and deformations, as well as model plastic deformations and transition to nonlinear problems. Based on this, several mining facilities were analyzed. The essence of the FEM is the approximate calculation of a system of the simplest equations for limited areas in order to determine the desired values. In modern practice of construction geotechnology, FEM has firmly established itself as the main tool for calculating building structures. A functional scheme of volumetric geomechanical modeling has been developed, which includes 6 stages: preparatory period; preparation of a priori information; formation of a basic model; numerical modeling; processing of calculation results; practical recommendations. The main novelty of the proposed technique is to identify the most dangerous section in the volume of the soil base, which allows us to fundamentally improve the accuracy of the geomechanical forecast.
