Abstract
RESUMO: Neste artigo analisa-se a estabilidade de taludes reforçados com estacas considerando a variabilidade dos parâmetros da geometria (comprimento e espaçamento) e posição das estacas, no intuito de avaliar o comportamento e a variação do fator de segurança com a implementação desse reforço em diferentes situações. Para tanto, foram empregadas ferramentas computacionais nas análises, por meio dos softwares Slide e RSpile que utilizam como base o método do equilíbrio limite para verificar a estabilidade de talude e as curvas p-y para análise das estacas, respectivamente. Ao modelar a introdução de estacas no talude, notou-se que esta prática aumenta a estabilidade do mesmo, além de se apresentar como uma alternativa tecnicamente viável ABSTRACT: This article analyzes the stability of pile-reinforced slopes considering the variability of the geometry parameters (length and spacing) and pile position, in order to evaluate the behavior and safety factor variation with the implementation of this reinforcement in different situations. With this aim, computational tools were employed in the analyzes, by the use of Slide and RSpile software, which use the limit equilibrium method to verify slope stability and p-y curves for pile analysis, respectively. When modeling the introduction of piles in the slope, it was noted that this practice increases the stability of the slope, and presents itself as a technically viable alternative for the slope to reach a normatively adequate safety factor. It was also observed that the optimal location for the pile in the analyzed cases is close to the crest slope and that the greater the spacing between piles, the less the effect in the improvement of the slope’s stability. It is concluded that the longer the pile length, the greater the slope stability, however, in this case, from 10 m of length, the increase in the safety factor was not very relevant.
