| چکیده | ||
| This research paper focuses on the load-bearing capacity of strip footings constructed on Geocell-reinforced sand slopes. The study included various experiments and numerical simulations to investigate the behavior of Geocell reinforcement when subjected to bending loads. The results indicated that when the height of the Geocell increased, the deep beam behavior was more pronounced, which suggests that the Geocell layer can act effectively as a deep beam. Additionally, the study revealed that when eccentric loading is applied to foundations near the sand slope crest, it decreases the footing's initial bearing capacity. When altering the geometry of a sand slope is not feasible and modifying the geotechnical properties of the soil is either impractical or expensive, the implementation of appropriate soil reinforcement can prove to be beneficial. Lastly, the findings of the study suggest that an increase in the number of Geocells can bring the foundation's load-bearing capacity closer to the loading capacity of a foundation on horizontal ground. | ||
