ANÁLISE DE TENSÃO-DEFORMAÇÃO E DE ESTABILIDADE GLOBAL EM MUROS DE ARRIMO DE FLEXÃO

Abstract

Containment structures aim at the stability of land masses in a location with marked topography. For many years techniques and theories have been studied, with the objective of knowing the behavior of these structures, in relation to the performance of the soil on the structure. The present work aims at the dimensioning of retaining walls in reinforced concrete (flexion) in a classical profile of different heights, after which, after due sizing, stability analysis, stress-strain analysis and global rupture analysis. Based on the loads and combinations of external loads that act on the containment, the principles of limit equilibrium are applied to relate the overall stability of this. And because, in this type of structure, depending on the excavation phases and/or the configuration of the internal rupture of the massif, they generate significant displacements for the support. As case studies, the retaining walls will have heights of 5, 6 and 7 meters, subjected to an overload of 20 kPa. Therefore, the study of strain-strain analysis aims at precision over conventional analyzes. For the study will be used the software Geo-Studio (2012), for stress-deformation analysis and thus evaluation of global geotechnical behavior.
