Correlación entre el ensayo EPOL y SPT para predecir la capacidad admisible de suelos arenosos y finos de consistencia rígida a muy dura

Abstract

Abstract: Thedesign of the foundations of houses with up to two floors, as stipulated in the Ecuadorian regulation NEC 15, is currently based on visually analyzing the reasonable quality of the soil, however, for the design of the foundations of engineering works it is necessary to have of the allowable capacity of the soil. By virtue of the aforementioned, formulations were developed to predict the admissible capacity of the soil, relating the SPT test and the EPOL test for local use. To meet this objective, thirty-six soil studies developed by the GICA company in the urban area of the city of Loja were analyzed, subsequently validated with field trials and alternative formulations. The results obtained showed a correlation factor of 1.96 for non-cohesive soils and 1.15 for cohesive soils, with which the formulations of Meyerhof (1974) were modified. For the validation of the analytical calculations, the formulations of Parry (1997) applied to cohesive soils, Mohr-Coulomb and calculations based on kinetic energy were used, resulting in the formulation of Meyerhof (1974), the most conservative.
