Construcción y análisis de un modelo experimental de muro de contención, fabricado con llantas recicladas usando suelo in situ

Abstract

This work development focuses on an experimental model analysis of a retaining wall by gravity constructed with recycled tyres and its comparison with a conventional retaining wall by gravity in such way that we can observe its geotechnical behavior, evaluate its boundaries and its scope. Some laboratory tests were carried out which allow us to characterize the material used and its properties. The construction of the model was done at the Universidad Distrital facilities, more specifically in the area assigned by the Technological headquarters physical resources department. A wooden Structure was constructed which allowed us to emulate a section of soil subjected to strong lateral loads, setting the wall’s geotechnical behavior and some deformations which were measured with high precision thanks to the topology equipment we acquired. A trapeze-shaped wooden box was constructed with specific dimensions and the recycled tyres were arranged so that they compact the soil material in-situ on the inside of the frontal side of the wooden box. This in order to generate a thrust load gradually adding granular material so that we can evaluate distances with high precision (millimeters) thanks to the help of topological equipment. Readings of each retaining element were taken as the load was increasing. This procedure was performed until it reached its point of failure. Thus, a parameter was obtained so that it could be compared with a conventional retaining wall. This Thesis work is presented as a study that might propose a guideline for the realization of other works related with this topic because there are plenty of other variables that can be considered due to the fact that they could alter the behavior of a structure constructed with recycled tyres.
