This study examines the performance of geosynthetic reinforced wall inserting vertical elements in conjunction with conventional horizontal reinforcements. In this system, similar to normal reinforcement, the selected granular material is compacted over the horizontal reinforcement up to the designed height and then another layer of horizontal reinforcement is laid down. Numerical investigations have been carried out using finite element software, PLAXIS. Geosynthetic reinforced soil foundation performance and its characteristics have been simulated with and without vertical reinforcement under static and dynamic loads. Numerical results show that the total settlement decreases by inserting inclined reinforcement in both static and dynamic loading in general, and particularly under seismic loading. A new bearing capacity formula incorporating the contribution of both vertical and horizontal reinforcements is also introduced based on the previously published studies and the outputs of this numerical simulation.
