Análisis paramétrico de la influencia de las variables morfología y aceleración sísmica, en la estabilidad de taludes cohesivos y friccionantes a partir de modelos de equilibrio límite

Abstract

It presents the results obtained from the realization of 280 limit equilibrium models of different types of slopes, in which both morphological variables and horizontal seismic acceleration were varied, for a dry and saturated state. An analysis of the data obtained using the Slide® Software was carried out, of which some were omitted, since they did not influence the stability of the slopes, which could be deduced by statistical methods. Stability charts were obtained for both cohesive and frictional slopes, for different values of seismic coefficient. It was found that the slope and height influence the geotechnical stability, decreasing the safety factors as they increase. Likewise, it was found that when the horizontal seismic acceleration increases, the safety factors decrease, which is consistent with the literature. The results obtained are relevant, since it contributes to the practice of engineering since stability chart were obtained that allow quick estimations for regular slopes, especially useful to determine critical heights in constructive slopes; emphasize that its application is limited and it is not intended to replace detailed geotechnical analysis of slopes with irregular geoforms and difficult water, stress and resistance conditions. The limitations of the work are detailed in the corpus of the article.
