Diseño de un sistema de estabilización de un talud, en el barrio “Espejo” de la parroquia Chillogallo, cantón Quito, provincia de Pichincha

Abstract

This degree project is aimed at the design of a slope stabilization system, these usually represent a great danger; specifically the unstable ones or those that are in the open without any protection or care, because they can cause different problems such as: human and material loss. For this reason, the design of a slope stabilization system was developed in the "Espejo" neighborhood of the Chillogallo parish, Quito canton, Pichincha province, using Geo5 software, applying technical specifications, standards, NEC 2015 and ACI 318-19, in order to implement innovative structures in the country, guaranteeing the stability and safety of the residents of the area. For this, an experimental and analytical study was carried out, which consisted of collecting information on the problems that have been occurring over time. Once the problem was identified, an in situ and laboratory study of the soil was carried out; the results obtained through the standard penetration test (SPT), soil classification and topographic survey determined that the intervention of a retaining wall was necessary. The finite element method option was used in the program by means of a seismic analysis, giving a safety factor of 0.47, thus demonstrating that it is an unstable slope. At present there are several retaining systems and to decide which type of structure to work with in the project, a classification was generated taking into consideration some characteristics such as: height, safety and economy, of which, only the anchored and nailed walls were left. The results were favorable since an average safety factor of 2.02 was obtained, demonstrating the advantages of using this wall, concluding that the nailed system is the best option.
