Analysis and re-sloping for slope stabilization in São José neighbourhood, João Pessoa, Paraíba, Brazil - case study

Abstract
The disorderly occupation of slopes and hillside 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 neighbourhood, located in João Pessoa, Paraíba, Brazil. The soil involved belongs to the Barreiras Formation and has been analysed geologically and geotechnically. Currently, a section of the slope experiences active seasonal mass movement, aggravated during periods of high rainfall. The objective is the slope stability analyses under natural conditions and perform a back analysis for the triggering of the mass movement. As a proposed stabilization measure, the analyses results show the necessity and feasibility to adopt slope flattening, along with surface drainage works and the application of vegetative protection using Vetiver grass as a stabilizing action to guarantee the safety of the residents in the region.
