Resumen
The development of the work is divided into two main stages. The first part comprises data collection, where technical and descriptive data of the terrain was determined by means of the topographic survey, which allows to accurately reflect the elements and geographical parameters of the slope under study. Additionally, the extraction of altered and unaltered samples was carried out for their respective analysis by the different laboratory tests which allowed determining the classification of the soil, cohesion, friction angle, plastic limits and liquid of the evaluated slope, this with the purpose to characterize the type of soil physically and mechanically. In the second stage, the modeling of the slope under study is evidenced through the SLIDE software, which determines the safety factor by different stability analysis methods. Consequently, the stability analysis of a slope located on one side of the road that connects Ibagué with the municipality of Anzoátegui Tolima was carried out, at a distance of 1,000 meters from the Calambeo neighborhood belonging to commune two (2) of Ibagué. This slope presents instabilities caused mainly by hydrological, geological and anthropic factors, generating a threat to the community that passes through the area. The different tests of the laboratories have allowed to have an approximation of the soil resistance parameters; These are: internal friction angle equal to 27.5 ° and cohesion 5 KN / m2. Additionally, the type of soil was determined by means of the granulometric test and the liquid (LL) and plastic (LP) limits index, the type of soil according to the unified soil classification system (SUCS), which classifies it in a SC (Sand with fine ). Taking into account the results corresponding to the geotechnical characterization that was carried out with soil samples taken at a depth of 1.5 meters, it was possible to show that the slope has a percentage of 77% to 86% of sand and 16% to 21% of fines. As an alternative solution to mitigate the risk of mass removal of the slope under study and after carrying out the analysis of the mechanical, geological and physical properties of the soil, it was determined as the most viable solution for the stabilization of the slope, the realization of a system of a retaining and terraced wall to later be revegetated.
