- This paper presents a numerical analysis of a Multi-layer soil structure improved with the use of geosynthetics. Numerical calculations using the finite element method (FEM) in ZSoil program were performed to determine the effectiveness of the applied reinforcement. In the solution of the problem, different boundary conditions were modeled to analyze the influence of several technologies on the construction of a rail road embankment, subjected to the effect of mining works. In the analysis, the applied loads correspond to the II category of the mining area. Mainly, the different load conditions reflect the intensity of the subsidence of the ground surface due to mining. The effectiveness of the soil reinforcement was determined using the comparison of the numerical calculations of displacements and strains for different scenarios. The reinforcement conditions were always contrasted among them and against the rail road embankment without any improvement. The displacements were measured at the surface of the rail road embankment. The slope stability of the embankment was measured using the soil shear strength reduction method (SSR). The obtained results show, that applying the appropriate reinforcement to the soil, the load/bearing capacity and the stability of the earth structure located in a zone of mining influence can be improved considerably.
