Ítem Acceso Abierto Análisis comparativo de métodos de estabilización para verificar el cambio de las propiedades físicas y mecánicas de suelos finos en la Parroquia Gualay, cantón Cuenca(Universidad Católica de Cuenca., 2025) Avila Taza, Ariel Steven; Alvarez Segarra, Diego Sebastián; González Maldonado, Marcos Darío; 0106429475; 0105826705Several laboratory tests, including sieve analysis, Atterberg limits, compaction test, load-bearing capacity (CBR), and direct shear and simple compaction tests, were conducted to understand the physical and mechanical properties of low-plasticy lime soils existing in the Gualay community. The results evidenced that this soil corresponds to a low-plasticy lime, whose characteristics are inadequate to withstand loads without prior treatment. Different lime stabilizers, bagasse ash, and asphalt emulsions were evaluated to analyze their influence on soil properties. Among them, lime at 7% proportion, applied as a substitute for natural soil, was the additive that showed the most favorable results. This percentage significantly reduced plasticity, increased maximum density, improved compressive strength, and optimized the soil’s bearing capacity. Cane bagasse ash, used at 10%, 15%, and 20% proportions, also contributed to improving certain physical and mechanical properties of the natural soil, especially in reducing plasticity and increasing strength, although to a lesser extent. Asphalt, in proportions of 2%, 4% and 6%, showed positive effects on soil strength and cohesion, but without exceeding the benefits obtained with lime. Finally, the behavior of soil stabilized with 7% lime was analyzed in detail, about the proportion substituted for the natural soil, confirming its effectiveness as a stabilizer. This treatment transformed the soil, making it more resistant and less susceptible to deformation.Ítem Acceso Abierto Determinación de parámetros geomecánicos mediante ensayos de campo y ensayos de laboratorio(Universidad Católica de Cuenca., 2025) Armijos Cango , Angel Danilo; Velasquez Ortega , Jovinson Francisco; González Maldonado, Marcos Darío; 1950052454; 1900862317This 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.Ítem Acceso Abierto Determinación de parámetros geomecánicos mediante ensayos de campo y ensayos de laboratorio(Universidad Católica de Cuenca., 2025) Armijos Cango , Angel Danilo; Velasquez Ortega , Jovinson Francisco; González Maldonado, Marcos Darío; 1950052454; 1900862317This 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.

This area is susceptible to landslides due to its mountainous geography, seasonal rainfall, and seismic activity. The study uses an integrated remote sensing and geotechnical engineering approach to analyze landslide typology and kinematics to improve risk management and land-use planning. Through geotechnical and geophysical analyses, the characteristics of the soils and their behavior in response to water infiltration were identified. The results show that soil saturation, combined with the presence of secondary scarps, contributes to slope instability. Furthermore, it was observed that the surface soils have low shear strength, which increases their vulnerability to landslides. Remote sensing provided accurate data on terrain morphology, which was complemented by geotechnical and geophysical studies to obtain a comprehensive assessment of soil conditions. Corrective measures, such as slope reinforcement and improved drainage, are recommended to prevent future landslides.Ítem Acceso Abierto Proyecto de Titulación embargado con fines de publicación de impacto(Universidad Católica de Cuenca., 2025) Malla Illescas, Jessica Catalina; Rojas Gutiérrez, Lessly Nicole; González Maldonado, Marcos Darío; 0107629537; 0302303797
