Definição de uma faixa pluviométrica crítica para deflagração de movimentos de terra em taludes rodoviários localizados no trecho da serra do mar da rodovia BR-376/PR

Abstract: Este artigo apresenta a metodologia empregada para a definição de uma faixa pluviométrica crítica para deflagra- ção de escorregamentos de terra nos taludes rodoviários da rodovia BR-376, no trecho da Serra do Mar Paranaense. A construção do modelo proposto partiu do entendimento e compilação da intensidade e duração tanto de eventos pluviométricos que resultaram em processos instabilizantes na região como daqueles que historicamente não deflagraram danos às encostas. A relação entre pluviometria e ocorrência … Show more

“…The Serra do Mar is a Brazilian mountain range with an average extension of 2,000.0 km, from the Rio de Janeiro state to Santa Catarina state. The area is characterized by a strongly undulated relief and considerable number of natural and arti(icial slopes (Victorino et al, 2017). Moreover, BR-376 Highway is an important traf(ic route for Brazilian products and passenger transports.…”

“…The precipitation data applied in this study was registered by two rain gauges denominated as RG1, which covers km 644 to km 654, and RG2, from km 656 to km 661, as illustrated in the map from Figure 1. The precipitation data is part of a research project focused on monitoring landslide risks (Victorino et al 2017, Trevizolli et al 2018and Ferreira et al 2018. Since the Serra do Mar is a region with high annual average rainfall and prolonged periods of rain, it is described as one of the places with the largest volume of rainfall in Brazil (Vieira and Gramani, 2015).…”
