Controle de estruturas de contenção de encostas com a utilização de veículo aéreo não tripulado (VANT/DRONE)

Abstract

The advancement of surveying systems and technical inspections of structures has contributed to the precision and, notably, the cost reduction of such inspections and analyses, significantly aiding in the monitoring of structures overall and proving particularly relevant in the behavioral analysis of slopes. Therefore, the aim of this study is to analyze the consolidation of a containment structure used to stabilize slopes of soil, rocks, or mixed materials, monitoring the movements of these masses which can lead to landslides, causing environmental and material damages, and in some cases, personal injuries. To achieve this, the chosen method was a combination of literature review and practical application, focusing on a case study using drones to assess displacement and the behavior of a gabion wall over a 5-year period. An orthomosaic of photos was created to monitor and measure potential movements of the gabion wall structure, specifically a box-type gabion wall in the city of Blumenau, SC, comparing it with surveys conducted in 2018, around the time of the structure’s completion. These results were analyzed using AutoCAD Civil 3D software, revealing a maximum movement of 3.0 cm at one point of the structure, while other points showed no significant movement, indicating the wall’s stability without substantial displacement.
