    This paper shows possibilities of a combination of finite element modeling and laboratory testing to investigate the reinforcing possibilities of the geogrids used for optimal track design. Deformation characteristics of different designs of the subgrade system with or without the reinforcing geogrid together with characterization of the bearing capacity of these designs are the main objectives of the study.

    Článek se zabývá možnostmi využití numerického modelování pro stanovení optimálního návrhu železničního spodku. Jednotlivé metody zvýšení únosnosti za použití různých druhů geosyntetik jsou srovnány s výsledky laboratorních zkoušek.
