"The calculation of the bearing capacity of the foundations is one of the most important geotechnical studies widely studied in the light of the different technical and mechanical parameters of the ground. The calculations are based on the marginal balance method. The method of marginal analysis and others, despite the variety of calculation methods, the difference between the bearing capacity factors is very large, especially at large angles of friction. The use of the finite element method in the geotechnical field is very common for complex problems that require the determination of stresses and strains at each point of the ground.This thesis concerns the realization of a numerical study using the program Interaction of Finite Element Soil Structures (PLAXIS 3D) and with a variety of treatments, including layers of geogrids and layers of compacted soil, as well as the change by cementing the soil with stone poles in order to evaluate the effect of changing these treatments on the bearing capacity of the foundation under Concentrated Vertical Load on Clay Soil.Finally, we used the program (MATLAB) to analyze and compare the results extracted from the mentioned methods and visualize them visually using the graphs and tables available in the program Develop an artificial intelligence model to predict the bearing capacity of soils reinforced by geogrids (case of square feet).
