| Reinforced soil structures are a good choice for coastal walls, dam building, especially at the base of the side walls of the guard bridges, waterways and watercourse side walls, settling basins and irrigation networks and drainage services. In this study, reinforced soil system for increasing the bearing capacity of the soil under the foundation structure was used an experimental model was developed for studying the behavior of geosynthetically reinforced sandy soil. Displacement vectors of the soil and bearing capacity of the strip footing measured in the reinforced mode and unreinforced mode until the impact of variable parameters such as the type of reinforcement, the number of reinforcement layers, the first layer of depth and width of layers also was examined. In addition, numerical models, as well as an experimental model by using Plaxis software was developed and the results were compared with laboratory results. Generally it was observed that the reinforced geogrid as compared to reinforced and unreinforced geotextile soils offers more resistance to load and has more bearing capacity. Further with increasing the number and width of the layers, the above mentioned phenomenon can develop. The evaluation of sandy soil reinforcement and the performance of physical modeling using PIV and numerical Simulationusing software Plaxis v8.2, suggested that the Size, of wedge failure in depth increases, and thus increases the bearing capacity of strip footing in reinforced state as compared to unreinforced state. | ||
