Caracterización Mineralógica y Geotécnica de las arcillas involucradas en los movimientos de ladera en la vía de Integración Ángel Felicísimo Rojas desde el cruce lateral de la Avenida Éxodo de Yangana hasta el redondel del Plateado

Abstract

Abstract: The Neighborhood Integration Road of the city of Loja presents a problem related to the instability of the slopes, which has resulted in the activation of a large number of hillside movements which cause damage to the road and the population, added to rainfall and physical-mechanical behavior of soils. Therefore, this research aims to establish a correlation between the mineralogy and geotechnical parameters of the clays present in the main slope movements of the neighborhood integration road through chemical and physical-mechanical laboratory analysis, among which the following stand out: SUCS classification, limits Atterberg, direct shear tests, triaxial; as well as the X-ray diffraction technique (XRD) to establish the mineralogical composition. The results obtained show the presence of low plasticity clays with friction angles not greater than 35° and their cohesion not greater than 2 Kg/cm². Using the XRD technique, it is determined that the clayey soils in the study area have the presence of muscovite, albite, beidellite and illite.
