Análisis para la estimación de estabilidad de un talud carretero ubicado en la vía Lateral de Paso Ángel Felicísimo Rojas

Abstract

Abstract: Mass movements have become one of the major disasters in Ecuador, especially in highways; the Lateral de Paso Ángel Felicísimo Rojas road located in Loja s city, has been affected by the great inconveniences that it presents when transiting due to the amount of these movements. For its analysis, two large geotechnical modeling software s SLOPE/W and PLAXIS 2D LE were used, in which three topographic profiles of the slope were modeled, considering three limit equilibrium methods, Bishop, Spencer and Morgenstern-Price. With this, it was obtained that the selected slope does present instability, with safety factors close to 1.0, as a mitigation measure it was decided to apply terracing, thus providing greater stability to the slope; however, the second topographic profile requires further evaluation, as it continues with values lower than 1.3, so it is recommended to place a support wall. In conclusion, the analysis of the slope showed that the road is actually at risk of mass movements, so it is necessary to analyze it concretely.
