Abstract
In this study, the results of full scale models are compared with the results of numerical analysis (Plaxis 2D) to provide the necessary knowledge to analyze geogrid-reinforced MSE walls under short and long-term loading conditions. The models were different in the flexibility of facing elements (with full rigid or full flexible face) and were the same in other parameters like number of geotextile layers, the vertical distance between layers and the strip footing distance from the wall. Specifics regarding the creep behavior of the geogrids and the stiffness for geogrid in short and long-term conditions are included in the study. The experimental results are compared with numerical results by considering the sidewalls friction effect. Based on the research findings, the maximum strains on reinforcement layers occurred under the strip footing load for upper layers. The lateral earth pressures decreased by increasing the distance from the strip footing load. The maximum wall deflection for flexible facing is more than the rigid facing and occurred in h/H=0.81 from top of the wall.
