Estudo comparativo entre muro reforçado com geossintético e muro de arrimo convencionais via método dos elementos finitos

Abstract

During the design of a containment structure, choosing the type of wall to be adopted is the first step to guarantee its proper functioning. One of the factors to be considered in these structures is the behavior in relation to deformations and displacements. Through this analysis, this work aimed to compare deformations and displacements between two different retaining systems, choosing the Soil Wall Reinforced with Geosynthetic (MSRG) and the conventional bending wall in reinforced concrete. For this, soil data were collected as well as the design of these retaining walls. For the analysis, a modeling was made in a geotechnical software that uses the Finite Element Method, Plaxis 2D. At the end, it was possible to find smaller values of absolute horizontal displacement and larger values of deformation, in general, for the bending wall. The relative deformation, for walls of 9 meters, presented better values in the MSRG and for 4 meters for the bending wall.
