Formulación de los métodos de estabilización del talud ubicado en el kilómetro 3.3 vía tamarindo salado, ibagué - tolima

Resumen

The present work focuses on establishing a stabilization method for a slope located at Kilometer 3.3 via salty tamarind; For the development of the same, the degree work "analysis of the stability of the slope located at kilometer 3.3 via salty tamarind, Ibagué - Tolima" was taken as a basis, from which secondary information corresponding to the topography and soil characteristics was extracted, to con These data carry out the calculation of the safety factor with different methods. Additionally, the hydrological study was carried out in the study area, with the analysis and condensation of the historical rainfall data extracted from the perales airport station, where maximum precipitation values were obtained recorded in the years 1972, 1988 and 2018, with values of 121.6 mm, 123.5 mm and 103.12 mm, respectively, which shows the high rainfall in the area and determines a maximum reception flow which is 1,184 LP * S, said flow is important for the design of works of Complementary drainage that ensures efficient transportation by reducing its speed with low-cost and environmentally friendly methods. To determine the most appropriate stabilization method, data on elevations, slopes, coverage type, soil type, resistance parameters, plasticity index and the respective modeling in the Slide software were analyzed to know the risk status of the slope when evaluating quantitatively in the safety factor, resulting in an unstable slope by having an index below 0.5 in the safety factor, which represents a vulnerability to possible mass removal events of the slope Therefore, three (3) conventional methods that best adapt to the characteristics of the area were evaluated, these methods were bolt-anchor, terraced with shotcrete and retaining wall with terraced; Of which the one that presented the best behavior in the stabilization of the slope was the bolt-anchor method, this when carrying out the modeling and raising the index of the safety factor above 1.1. However, it is important to note that said conventional method is very expensive to manufacture, so that the use of bioengineering methods is proposed for the present work, such as carvings with guadua that form terraces that improve the slope stability and significantly reduces manufacturing.
