Finite Element Analysis of Strip Footing on Geogrid- Reinforced Soil
The low bearing capacity of soil can cause the foundation to settle or even collapse due to weak or soft soil, and inadequate compaction, or compressible materials like clay. Therefore, it is crucial to research soil enhancement methods to prevent such issues. This paper's purpose is to investigate the impact of various dimensions of reinforced foundations on the bearing capacity characteristics. The study evaluated various parameters, such as displacements, stresses, strains, and failure mechanisms, which are critical for understanding the performance of foundations. Numerical analysis has been utilized to simulate the response of reinforced soil-foundation systems under different loading and boundary conditions. A set of conditions was examined by varying several parameters related to the geogrid reinforcement. These parameters involved the depth of the initial reinforcing layer, the perpendicular distance between layers, the number of layers, and the width of geogrid layers. The study's findings demonstrate that the addition of soil reinforcing improved the performance of the strip footing. Findings regarding the optimal parameters for geogrid reinforcement (geogrid width = 2B, depth of the top geogrid layer = (0.33 to 0.5)B, vertical distance between reinforcement layers = (0.25 to 0.33)B, number of layers = (3 to 4). Additionally, the efficient depth of the geogrid reinforcement, approximately determined (1.5B).
