The present investigation is oriented to carry out a comparative analysis in the estimation of bearing capacity using 4 calculation equations for the design of Surface Foundations and an SPT test, these equations belong to: “Terzagui, Meyerhof, Hansen and Vesic” being used in the News in our local environment. In the preparation of this thesis, open pit excavations (gaps) were carried out randomly and from which samples were extracted for testing in the soil laboratory, said soil samples belong to the area of Tambocancha, Chinchero District of the Province from the Urubamba Department of Cusco, the tests that were carried out were both characterization and resistance to cutting. For the development of the various tests, we worked in the soil laboratory of the Andean University of Cusco. The study was applied to the Design of Surface Foundations such as insulated footings, combined footings, connected footings, foundation beams and foundation slab. It was concluded that the calculation equations have a greater permissible capacity with respect to the results of the SPT test. It was also found that the calculation equations, (Hansen, Meyerhof, Terzaghi and Vesic), are structured according to the cohesion of the soil (c), angle of internal friction. It was shown that the water table increases the bearing capacity of the results obtained from the calculation equations for a cohesive soil considering that the clay is submerged and has a specific submerged or buoyant weight that causes the pore pressure to generate a foundation force. It was possible to verify that the elastic settlement decreases according to the depth, verifying that the depth is lower due to one of the factors (A2) that were used for the calculation of the elastic foundation settlement on saturated clay is a function of 𝐷𝑓/𝐵 which is the relationship between the depth of foundation and the width of the shoe It was possible to verify that, if there is a direct relationship between the forms of the types of foundations based on their respective ultimate load capacities.
