Item Modelo de una fundación circular a escala para medir esfuerzos en suelo granular usando celdas de cargas.(Universidad Tecnológica Nacional Regional Córdoba., 2018) Aiassa Martínez , Gonzalo Martín; Arrúa, Pedro Ariel; Eberhardt , Marcelo; Useche Infante, Danny José; Useche Infante, Danny JoséEn este artículo se presentan los resultados de una serie de ensayos de carga realizados con un modelo de fundación apoyado en arena. El objetivo de este estudio es medir los esfuerzos verticales que se producen dentro del suelo al aplicar las cargas con la fundación. Se utilizó un modelo de fundación circular y la arena se dispuso en un tanque circular metálico, completamente rígido de 60 cm de diámetro y 45 cm de altura. Los esfuerzos se midieron con celdas de carga de diafragma. Se determinó el efecto de la densidad del suelo en la distribución vertical de esfuerzos en la arena. Los resultados mostraron que la inclusión de las celdas en la masa de suelo produjo una alteración en el comportamiento esfuerzo-asentamiento de la fundación.Item Effect of geogrid reinforcement on interface for a stratified embankment.(GEOMATE, 2016) Useche Infante, Danny José; Aiassa Martínez , Gonzalo Martín; Arrúa , Pedro Ariel; Eberhardt , MarceloReinforced granular embankments are often placed on soft soil strata for an efficient and economical transfer ofsuperstructure load. This paper describes laboratory tests on circular footing supported on unreinforced and geogrid-reinforced granular soil. Two types of geogrid layer, uniaxial and biaxial geogrid, were placed at the interface of sub-base soil and granular base of an embankment formed on soft ground to support shallow foundations. Load test were conducted with the aim to determine the performance improvement of the circular footing due to the provision of both types of geogrid reinforcement in the soil. Also studied the effect produced by anchoring geogrid layer at the edge of the mold sample. The results showed that the inclusion of a geogrid layer at the interface of sub-base soil and granular base increase the magnitude of the footing bearing capacity and decreases the settlement of the system. The study shows that the type of geogrid used has direct influence on stress-strain behavior of soil-geogrid system and better results occurred when the geogrid was anchored to test mold.Item Effect of geogrid reinforcement on interface for a stratified embankment(Geotech., 2016) Useche Infante, Danny José; Aiassa Martínez, Gonzalo Martín; Arrúa, Pedro Ariel; Eberhardt, Marcelo GabrielReinforced granular embankments are often placed on soft soil strata for an efficient and economical transfer of superstructure load.
