Inspeção de taludes rodoviários em relaçãoà estabilidade

Abstract

According to data from the Federal Highway Police processed by the National Transport Confederation (CNT), more than five thousand deaths on federal highways were identified in 2020, with approximately one hundred of these fatalities caused by landslides on highways. With that in mind, the present work sought to elaborate an evaluation spreadsheet referring to the stability of natural slopes or built along the roadsides, using as a practical example for its conception the first 89 kilometers of the Federal Highway BR – 232/PE, connecting the municipalities from Recife to Gravatá. This assessment was carried out by collecting data on the types of soil found in the state, as well as the most visible profiles found on the slopes and their morphological characteristics. The BR – 232 stretch was chosen due to its history of landslides and accidents in general, with the aim of having a dangerousness parameter, linked to the number of accidents and deaths found along the first 89 kilometers of the highway, which facilitated the correlation between these values and the scoring system that was implemented for the stability analysis form, serving as an aid in the delimitation of risk zones in the stretch, facilitating the visibility of possible interventions.
