Análisis de mejora de características geomecánicas del suelo con pasto vetiver

Abstract

Abstract: The research focuses on developing apparent improvements in the properties soil geomechanics through the application of Vetiver grass. Recognized for his ability to increase soil stability, this grass has sparked interest in geotechnical and environmental engineering. The research, carried out in the Rumizhitana area, via Loja - Catamayo, its main objective is to evaluate the impact of Vetiver grass on the geomechanical characteristics of the soil, especially in resistance, cohesion and Loading capacity. The characterization of the area includes the identification of vulnerable areas and the presence of Vetiver vegetation through taxonomy based on literature data and observations in field. The SUCS classification reveals the presence of silty soil in the surface layer and a mixture of clay and silt in deeper layers. The results indicate variability in the distribution of water at different depths, with possible implications for land management. In terms of mechanical parameters, Triaxial and direct shear tests show greater resistance and stability of the soil in the presence of Vetiver, with a decrease in plasticity at greater depth. The Comparison of resistance with and without Vetiver roots reveals apparent changes in the cohesion and friction in silty clay soils. Additionally, the importance of consider variations in different depths and soil types when implementing techniques bioengineered with Vetiver grass. Taken together, the results support the hypothesis that Vetiver can have a significant impact on improving geomechanical properties ground.
