Comparação estatística entre as equações de ajuste da curva de retenção de água em solo de cobertura de aterro sanitário
Resumo
Os solos residuais resultam do intemperismo químico, logo suas características dependem de fatores ambientais, além de origem, topografia, drenagem e idade geológica. Na condição não saturada, o comportamento dos solos é condicionado pela sucção, que se refere ao estado do solo sob pressão reduzida. O objetivo deste estudo é comparar as equações de ajuste da curva de retenção de água no estudo de solos tropicais insaturados através da técnica do papel filtro e a análise analítica dos dados obtidos neste ensaio. Ao realizar a análise dos parâmetros de avaliação estatística utilizados neste estudo e a proximidade de seus valores às condições de contorno necessárias definidas para a equação para explicar o comportamento de sucção do solo à medida que ele perde umidade naturalmente para o meio ambiente, foi verificou que a equação de Van Genuchten parecia ser a mais adequada.
