Influencia de la cohesión aparente generada por raíces sobre la estabilidad de un talud natural en las dunas de Re？aca

several researches have shown that vegetation plays a key roll in preventing displacements of soil masses, particularly of surficial displacement of slopes. thus, tree roots provide a reinforcement system that depends on its structure and distribution. this article presents a research applied to a natural slope in re？aca-chile, and the objective is to analyze the apparent cohesion developed as a result of roots existing in the slope. the analysis of the problem was conducted for two scenarios: static loading and a pseudostatic loading based on data collected after the 1985 chile earthquake (mw7.8). from this analysis, different factors of safety and seismically induced displacements have been estimated.
