... Analogamente aos sensores convencionais, uma curva de calibração do sensor é necessária para derivar os valores de deformação da quantidade de medição de frequência. No entanto, os fabricantes de cabos sensores de fibra óptica muitas vezes não fornecem seus próprios parâmetros de calibração e consultam os valores na literatura especializada, o que pode resultar em erros no monitoramento (Moser et al., 2016). ...

This article presents emerging technologies for inspection, monitoring, and analysis of slopes along the Carajás Railroad (EFC), developed within the research project of the VALE Under Rail Chair. A landslide susceptibility map using remote sensing data and monitoring by InSAR and LiDAR drones is utilized. Critical slopes are characterized and monitored with remote instrumentation, fiber optics, and low-cost sensors, following the methodology under development at GeoInfraUSP. The present and future behavior will be studied through numerical simulations considering the effect of vegetation, infiltration, and climate change. The methodology under development can be extended to other railways. Keywords: Inspection, Monitoring, Slopes, Railway, Climate Change.
