Geotextiles are successfully implemented for the reinforcement of soils to solve certain settlement as well as bearing capacity problems in difficult ground conditions. Furthermore, geotextiles are used for the stability of man-made slopes as well. In this study, the performance of geotextiles applied for soil improvement is evaluated by considering various geotextile types that have different axial stiffness rates. The stiffness values were compared via a finite element method (FEM) based software namely PLAXIS 2D. As a case study, Kayseri Organized Industrial Site in Turkey was chosen for the performance assessment of these geotextiles for a specific soil profile. Besides, the rate of settlement, axial force and the effective stress variation during the application of geotextiles was also evaluated by the FEM-based approach. The selected geotextiles were examined using scanning electron microscope (SEM) analyses after tensile strength tests. The results indicate that the axial stiffness (EA) has great impact on the degree of soil settlement and axial force. The settlement of subsurface soil decreases with an increase in stiffness of reinforcement.
