3D Approach of Arching Effect in Basal Reinforcement Layer

Several analytical and numerical models have been introduced and tested to assess the arching effect on piled embankment. Given the prevalence and popularity of this case, it is not easy to select and recommend best design methodology. Used materials and types of reinforcement play an important role when it comes to designing high-speed railway lines in difficult geological conditions. Our numerical approach by 3D FEM analysis was focused on the influence of geometry to the arching creation in basal reinforcement layer, especially to distribution of internal forces in high tensile geogrids.
