Análise comparativa do dimensionamento de muro de arrimo em concreto armado para dois tipos de talude de terra

Abstract

The containment of slopes is a subject of great relevance at the present. With the expansion of the inhabited areas there was a need to study containment techniques aimed at building safety. In this sense, a correct choice of the type of structure can influence the whole logistics of the construction, in which the execution and financial factors must be analyzed in the design of a containment project. This work presents an introduction about the types of containment structures, as well as a dimensioning of a reinforcing wall in reinforced concrete or bending wall, for two different soils, from the pre-dimensioning to the choice of armature. An analysis of the stability of the structure is performed, as well as the calculation of the forces acting on the wall coming from the land mass and the overloading and dimensioning of the proper dimensions for the wall. The armature of the structure is also calculated, and finally a cost analysis for the specific services in the execution of contention. The dimensioned containment has the main advantage of reducing the volume of the support structure, in comparison with walls of gravity its volume is considerably smaller, thus bringing more space to the accesses around the work, another valid aspect is its ability to contain relatively large spans, all these factors led to the choice of reinforced concrete wall.
