Comparação de estruturas de contenção com variação de altura em obras de infraestrutura

Abstract

Although recurrent use of retaining walls in different situations, there is few technical and scientific material on the subject. The Brazilian standard has a large deficiency in this area and it is often necessary to use international standards. This fact creates a difficulty for engineers when choosing which structure is suitable for each situation. In this way, often the decisive factor for using a retainer is the familiarity of the project. However, containment works have high values and, in the case of infrastructure works, this value becomes worrying when analyzing situations in which there are hundreds of meters of retaining wall. Thus, the elaboration of materials that assist in the adequate choice of structures is fundamental for the Brazilian scenario. The present work aimed study the use of three types of retaining wall (cyclopean concrete, reinforced concrete and anchored retaining wall) in infrastructure works. For this purpose, calculation tables were developed to design the three structures. In addition, for a better analysis, the height of the three types of wall were varied, thus obtaining a material consumption for each solution. In addition, the limitations and advantages of each structure were raised. In this way, the work aimed contribute technically to expand the knowledge about containments and assist designers in choosing suitable solutions for their projects.
