Abstract
The purpose of this research is to compare the values of the admissible capacity in shallow foundations using the equations of Terzaghi, Meyerhof, Hansen and Vesic, based on the characteristics of the soil in the "El Mirador" Urbanization in the Cajabamba District. Seven pits were carried out, in which a series of tests were carried out, including the measurement of moisture content, natural density, specific weight, granulometric analysis, plasticity indices and triaxial compression. These tests allowed the soil to be classified using the SUCS system, identifying layer one as poorly graded sand (SP) and layer two as well graded sand (SW). In addition, the admissible capacity of the soil was calculated using the methods of Terzaghi, Meyerhof, Hansen and Vesic. The results revealed that, according to the Terzaghi method, the values range between 7.57 kg/cm2 and 10.80 kg/cm2, compared to the values obtained by Meyerhof (10.38 kg/cm2 - 14.68 kg/cm2), Hansen (11.70 kg/cm2 - 16.53 kg/cm2) and Vesic (11.78 kg/cm2 - 16.61 kg/cm2). In conclusion, it is observed that Terzaghi's method provides greater structural safety compared to the Meyerhof, Hansen and Vesic approaches.
