Correlación entre las propiedades geomecánicas cohesión (c) y ángulo de fricción (ø) obtenidos con ensayos triaxiales uu y los parámetros de resistencia del cpt (fs y qc)

Abstract

The following study was conducted to establish correlations between the geomechanical properties of cohesion (C) and friction angle (Ø) bases on the cone resistance (qc) and friction (fs) parameters obtained from the Cone Penetration Test (CPT) in mixed soil (sand and silts). The aim was to evaluate these geomechanical parameters (C, Ø), archieving cost reduction and optimization in various geotechnical designs. Once the exploration point were defined, CPT test were conducted to obtain resistance values (qc) and (fs). Subsequently, undisturbed soil samples were collected and subjected to UU triaxial tests (unsatured) in the soil mechanics laboratory to determine the geomechanical parameters (C) and (Ø). Next, linear regression methods were employed to analyze the relationship between the variables obtained in the field and those determined in the laboratory. The results presented the equations derived from correlations and along with a detailed analysis of statistical data.
