Aplicación de métodos probabilísticos a la estabilidad de taludes, considerando reforzamiento del talud con geosintético

Abstract

Abstract: In the analysis of slope stability there are two methodologies that allow analyzing this field, such as the deterministic and probabilistic methods. Deterministic methods are not sufficiently effective due to their limitations in the variability and unreliable of geomechanical parameters, so they are often replaced by probabilistic methods. The present investigation studies the stability of slopes in the side road of the city of Loja, considering the probabilistic analysis subjected to limit equilibrium. The development of the research includes the geomechanical characterization of the soils in two stages for the generation of safety factor values using the Janbú methodology and then using the variability of cohesion and friction angle applying the Monte Carlo methodology on a digital model generated in Rocscience software. The probabilistic evaluation allowed to determine the degree of instability of the slope, for this a mitigation measure was proposed by reinforcing the slope with geosynthetics, considering UX geogrids type higher values of FS are obtained that represent an acceptable stability.
