Bioingeniería aplicada mediante simulación para la estabilización de taludes de carreteras

Abstract

Abstract: The instability of slopes on roads is one of the problems with the highest incidence in the country and to which a timely solution must be given. Within the San Cayetano neighborhood, the study area is located, next to the main road that connects the cities of Loja and Zamora, whose conditions are appropriate for the analysis and application of stability through bioengineering. For the present research, the analysis of the stability effect produced by plants on different types of soil was carried out, varying the geometry, the angle of inclination and considering the effect of the water table. The method of analysis worked through numerical modeling is the limit equilibrium, under the Mohr-Coulomb break criterion, analyzing the stability of the slope under study as for the type slopes. It was also determined the choice of the most used plant species in the stability of slopes and of which the parameters of cohesion provided by their roots and the depth at which they act are known, considering important the species of non-natives and suggested species that can adapt. Finally, through the development of statistical analysis based on the reasoning of apparent cohesion provided by the roots of the plants in the soil-root anchoring system plus soil cohesion, the best plant species for slope stability was established.
