Abstract

fetched live from OpenAlex

Permeabilidade é uma propriedade de extrema importância para dimensionamento de diferentes tipos de obras de engenharia e é quantificada através do coeficiente de permeabilidade. Apesar do grande uso, ainda existem questionamentos sobre a melhor forma de determinação do coeficiente de permeabilidade. As principais questões são: (1) o tipo de método a ser utilizado e (2) a representatividade de amostras em solos tropicais. Neste contexto, objetivou-se neste trabalho a avaliação da permeabilidade de um solo laterítico, através da comparação de valores de coeficiente de permeabilidade determinados por ensaios in situ e em laboratório. Para tanto, escolheu-se o solo laterítico do Campo Experimental de Engenharia Geotécnica (CEEG) da Universidade Estadual de Londrina (UEL) e quatro equipamentos: permeâmetro de Carga Constante, permeâmetro de Carga Variável, permeâmetro de Guelph e Infiltrômetro. Os resultados mostram que, com exceção do permeâmetro de Carga Constante, todos os métodos apresentaram valor médio de coeficiente de permeabilidade da ordem de 10-3 cm/s para coeficientes de variação de 37% a 92%. A heterogeneidade da estrutura do solo laterítico (em macro e microporos) é o provável condicionante da variabilidade encontrada.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
