Determinación de parámetros geomecánicos mediante ensayos de campo y ensayos de laboratorio

Abstract

This study aimed to characterize the geotechnical properties of the underground at the Catholic University of Cuenca - Azogues campus within an area designated for future construction. To this end, geophysical and geomechanical methods were integrated, utilizing a methodology that included excavating a trial pit, conducting two Standard Penetration Tests (SPTs), and implementing a Multichannel Analysis of Surface Waves (MASW) seismic refraction line. An undisturbed sample was obtained from the trial pit, allowing for the determination of particle size distribution, moisture content, Atterberg limits, simple compression, direct shear, and triaxial tests. The SPTs complemented the data obtained from the pit, allowing for the determination, through correlations, of cohesion, internal friction angle, and allowable bearing soil capacity. Additionally, wave velocities (Vs) were measured to identify the soil type. The MASW seismic refraction line, measuring 24 meters long, determined the Vs and P-wave velocities (Vp), identifying different soil strata down to a depth of 30 meters. The results provide information specific to the area where the samples were taken; therefore, to expand knowledge of the soil conditions throughout the site, additional surveys would be necessary within the property.
