Análise e proposta de baixo custo para estabilização de talude no bairro São José em João Pessoa-PB - estudo de caso

Abstract

The disorderly occupation of slopes and hills by socioeconomically vulnerable populations has caused changes in vegetation and topography in these areas, which can accelerate the occurrence of mass movements, resulting in material and human losses. Although there are available technologies and slope stability solutions, they are often inaccessible to communities in high-risk areas due to high costs and lack of investment from public authorities. This study was conducted in the São José neighborhood, located in João Pessoa, Paraíba. The soil involved belongs to the Barreiras Formation and has been analyzed geologically and geotechnically. Currently, a section of the slope experiences active seasonal mass movement, aggravated during periods of high rainfall. The objective is to analyze the slope stability under natural conditions and perform a back analysis for the triggering of the mass movement. As a proposed stabilization measure, the results indicate the necessity and feasibility of adopting slope flattening, along with surface drainage works and the implementation of vegetative protection using Vetiver grass as a stabilizing action to ensure the safety of the residents in the region.
