Parámetros de resistencia al corte en muestras de suelos del cantón Quito, utilizando la caja de corte directo en condiciones de humedad natural y saturada

Abstract

This research presents the identification of shear strength parameters in soils of Quito city, both under natural and saturated moisture conditions, with the aim of understanding critical geotechnical properties that impact slope stability, foundation settlements, embankment stability, soil bearing capacity, among others. Through geotechnical analysis, laboratory tests were conducted to assess the shear strength of three sites within the Metropolitan District of Quito. The focus was primarily on evaluating key parameters, such as cohesion and internal friction angle, under both natural and saturated conditions, considering the specific geotechnical characteristics of the soils in the area. Additionally, the study analyzed how moisture influences these parameters, providing a comprehensive understanding of soil shear strength in saturation conditions in Quito, crucial information for civil engineering design. This research also offers practical recommendations for civil engineering, with the goal of improve the safety and proper performance of structures in these particular conditions, contributing to local geotechnical knowledge significantly and providing a guideline for future research related to shear strength of soils with similar properties.
