Estruturas de contenção aplicadas em rodovias

Abstract

The present work had as objective to analyze the possible uses of containment structures applied in highways, where a case study was made in the highway BR-101/RN near the Avenue Maria Lacerda Monte Negra that used a containment structure composed of excavated piles providing a possible possibility of replacement of the current containment of the highway with another type of containment that is more practical, more economically viable and that meets the constructive and structural normative specification. The type of containment chosen for the analysis was that of armed land, which currently has more prominence in this area of highway containment, presenting to be more economically viable, more practical, with less construction time and greater durability of the rest of the market. Taking as the theoretical framework for this work a cost analysis conducted by Gaspar (2016), where the cost of three containment structures (gravity wall, armed land and reinforced soil) was analyzed, in which, it may be concluded, as the fastest, practical, durable and cost-effective armed land technique.
