Desafios Geotécnicos e Governança Ambiental na Rodovia BR-319 - Uma Análise da Formação Içá e da Sustentabilidade na Amazônia.

Abstract

Desafios Geotécnicos e Governança Ambiental na Rodovia BR-319 - Uma Análise da Formação Içá e da Sustentabilidade na Amazônia. A rodovia BR-319, que liga Manaus (AM) a Porto Velho (RO), é um eixo estratégico para a integração da Amazônia Ocidental, atravessando áreas de altíssima sensibilidade ecológica. O estudo destaca que a via está implantada sobre a Formação Içá, o que impõe um desafio geotécnico complexo devido à presença de solos instáveis, argilas de alta compressibilidade e estratificação heterolítica. Tais condições exigem soluções de engenharia específicas, como o uso de drenos verticais, estabilização de taludes com drenagem profunda e a aplicação de pavimentos robustos e flexíveis para suportar recalques diferenciais. No âmbito da gestão, o projeto enfrenta o risco socioambiental de expansão do desmatamento ilegal, conhecido como padrão "espinha de peixe". A viabilidade da rodovia e a renovação de sua Licença de Operação (LO) estão condicionadas à execução rigorosa do Plano Básico Ambiental (PBA), que inclui o monitoramento da fauna, a proteção hídrica e a fiscalização contra a grilagem de terras. Conclui-se que o sucesso da BR-319 depende da harmonização entre a engenharia de alta performance e uma governança interinstitucional eficaz para garantir a conservação do bioma. Palavras-chave: Rodovia BR-319, formação Içá, geotecnia, Licenciamento Ambiental, sustentabilidade amazônica. Abstract Geotechnical Challenges and Environmental Governance on the BR-319 Highway - An Analysis of the Içá Formation and Sustainability in the Amazon. The BR-319 highway, connecting Manaus (AM) to Porto Velho (RO), serves as a strategic axis for the integration of the Western Amazon, traversing areas of extremely high ecological sensitivity. This study highlights that the road is built upon the Içá Formation, posing complex geotechnical challenges due to unstable soils, high-compressibility clays, and heterolithic stratification. Such conditions require specific engineering solutions, including vertical drains, slope stabilization with deep drainage, and the application of robust yet flexible pavements to withstand differential settlements. Regarding management, the project faces socio-environmental risks related to illegal deforestation, known as the "fishbone" pattern. The highway's viability and the renewal of its Operating License (LO) are contingent upon the rigorous execution of the Basic Environmental Plan (PBA), which encompasses fauna monitoring, water protection, and law enforcement against land grabbing. It is concluded that the success of BR-319 depends on harmonizing high-performance engineering with effective inter-institutional governance to ensure the conservation of the biome.
