In Slovakia, construction process already begins in less suitable locations. Such a location is also situated in Podhorie, small village near the city of Žilina. The subsoil is formed by high-plasticity clay with claystone in lower position. This article deals with the analysis of the influence of various input parameters as well as R inter mesh discretization on the determination of safety factor – M SF . The Mohr-Coulomb constitutive model was used in numerical model with respect to availability of input parameters. The ability to identify the parameter with the biggest impact on the resulting value of safety factor is an indisputable benefit. Various studies have been published on this topic. In our case, cohesion c had the biggest influence on the M SF parameter when reducing shear parameters. In the future, the authors will compare the achieved results of numerical modelling with the actual deformations of the structure.
