Abstract: The paper analyzes the procedure of creating three-dimensional models of discontinuous and tectonic faults for numerical modeling problems using the finite element method. A number of uncertainties arise in the geomechanical analysis of the stress-strain state of faults due to the choice of the type of their computational geological model, e.g. the dislocation, domain or dynamic impact zone models. A comparative analysis of the stress-strain state in the mentioned computational geological models is performed. The geological and structural models are based on the geological sampling data collected in the investigated area. Special attention is paid to building the structural-tectonic model with account of discontinuous and tectonic faults that affect the deformations and stresses of the rock mass. As the result, the most preferable of the three given options is the computational geological model with the dynamic impact zone. The domain of the dynamic impact zone with lower physical and mechanical properties makes it possible to cover the entire potential volume of the rupture zone.
