Caracterização geotécnica dos solos de subleito ferroviário: investigações de campo e laboratoriais

Abstract: O avanço dos sistemas de transportes impulsionou o desenvolvimento de novos estudos para análise do desempenho do pavimento em resposta a diferentes tipos de solicitações. Associada ao crescimento do setor, à necessidade de duplicação de vias e ao aumento de carregamento das linhas em operação, a investigação do subleito é considerada um elemento fundamental para a garantia da qualidade do desempenho do pavimento e para a operação segura e confortável dos veículos ferroviários. Este artigo teve como objetivo p… Show more

“…The vegetation of the municipality region is classified as seasonal semideciduous forest (subdeciduous tropical forest) with an alluvial aspect, containing secondary vegetation and agricultural activities [30] (Figure 2a). Furthermore, the most common soil types in the study area are red-yellow argisol and red oxisol [31] (Figure 2b), which are typical of areas between the tropics, being commonly named "tropical soils" [32,33]. The predominant climate type of the region is Aw (tropical dry, according to Köppen-Geiger), with average annual rainfall between 1100 and 1200 mm, characterized by two very distinct seasons: rainy summer-spring, with December being the month with the highest rainfall, and dry autumn-winter, with August being the driest month [28,29].…”

Besides the historical irregular occupation of the margins of the Muriaé River, the Muriaé River basin has been subject to a deforestation process since the 19th century [34,35].…”

“…The most common soil types in the region of Itaperuna are red-yellow argisol, dark red argisol, red oxisol, orange oxisol, and gleysol [53]. These soils are typical of areas between the Tropics, being commonly named "tropical soils" [54][55][56]. The climate of the region is Tropical with dry winter (Aw, according to the Köppen-Geiger climate classification), characterized by two very distinct seasons: rainy summer-spring, with December being the month with the highest rainfall, and dry autumn-winter, with August being the driest month [57].…”

Dessa forma, são necessários estudos específicos para cada tipo de solo (Carvalho e Souza, 1990;Conciani, 1997;Futai, 1997;Miranda Junior, 2006;Campos et al, 2019). Fisicamente, o solo é composto por vazios e um esqueleto sólido que basicamente depende das propriedades minerais das partículas e a água presente na matéria.…”
