Modelación numérica de la estabilidad de taludes frente al reforzamiento con pasto Vetiver

Abstract

Abstract: This study evaluates the effect of vetiver grass roots on slope stability. To this end, root properties, soil geomechanical characteristics, and other necessary data were determined, based on previous research conducted by other authors. Numerical models were developed using different modeling approaches. Five root placement positions were analyzed, and two growth stages were evaluated: at 9 months and 2 years. Through experimentation, it was found that the roots improved the factor of safety in all positions evaluated. The most viable position was the "toe and a half slope." On the other hand, the least effective placement position, which could even be detrimental, was the "crown and a half slope." The research is robust, as each modeling approach includes all the parameters and considerations necessary for a complete evaluation, allowing researchers or readers to select the most appropriate method based on the ground conditions they wish to analyze and their own criteria.
