The research aims to analyze the correlations of allowable pressures for shallow foundations in fine soils, considering different variables such as criteria (allowable bearing capacity and permissible settlements); estimation methods (analytical and numerical); and geotechnical characterizations (data collection method and type of shear strength). In the criterion for allowable bearing capacity, the analytical methods encompass the theories of Terzaghi, Meyerhof, Hansen, and Vesić. On the other hand, for the criterion of permissible settlements, the Bowles method is utilized. Meanwhile, the numerical method employed is the Finite Element Method (FEM), applicable to both the criteria of allowable bearing capacity and permissible settlements. Geotechnical characterization of soil mechanical properties is conducted through Unconfined Compression Triaxial (UU) tests and correlations of the Standard Penetration Test (SPT). Based on the N60 values obtained from the SPT tests, 12 correlations for undrained shear strength, 4 for equivalent friction angle, and 3 different modulus of elasticity are established. Additionally, simulations were conducted for 3 types of foundations (square, circular, and continuous), at 4 levels of embedment: 0.20 m, 0.60 m, 1.20 m, and 1.80 m. The adopted methodological design is non-experimental, with a quantitative and correlational approach, employing a hypothetical-deductive method as hypotheses are subjected to statistical tests. Exploration was carried out through 8 test pits and 8 boreholes up to 3 meters deep in the APV. Villa El Chaparral, San Sebastián (Cusco), collecting a total of 72 samples, resulting in the determination of 39,936 allowable pressure values. The results indicated a moderate correlation between analytical and numerical methods for bearing capacity (rho = 0.495, p < 0.001) and for pressures due to permissible settlements (rho = 0.317, p < 0.05). Furthermore, a stronger correlation in geotechnical properties was determined for analytical methods compared to numerical methods in determining allowable pressures. In conclusion, numerical methods offer higher correlation values and less variability compared to analytical methods. It is noteworthy that, despite significant differences in allowable pressure values determined by different methods (p < 0.001), the less conservative methods were Meyerhof and Vesić, while the most conservative values were determined by the Bowles method.
