Analysis and design of containment structure in eruption talud rupture: case study

Abstract

The erosive processes are essentially based on the disintegration, transport and deposition of the soil, with the action of erosive agents water, winds and or ice. It is known that the soil has a capacity to withstand stresses, however, if its characteristics are altered, the load capacity will undergo changes, being able to become a fragile soil, a factor with the characteristic of diminishing soil resistance is erosion . In view of the above, the article proposes to analyze and size a gabion structure to contain the soil erosion process located in the municipality of Porto Nacional, in the vicinity of the São João stream, on Padre Luso Avenue. It should be noted that this rupture is less than one meter away from a building and if it persists it will reach another five surrounding buildings. In this study, soil characterization tests were carried out. In the stability analysis of the gabion structure proposed for containment of the slope, the sliding, tipping and load capacity criteria were verified according to NBR 11682/1991. In addition, the overall analysis of the slope / wall system was also performed. It was found that the proposed structure meets the technical safety requirements.
