29. A STUDY OF SOIL TERMO-HYDRAULICS PROPERTIES REQUIRED AT THE APPLICATION OF THE THERMAL DESORPTION / AVALIAÇÃO DE PROPRIEDADES TERMO-HIDRÁULICAS DE SOLOS REQUERIDAS NA APLICAÇÃO DA TÉCNICA DE DESSORÇÃO TÉRMICA
A presente tese apresenta uma abordagem sobre a técnica de dessorção térmica na remediação de áreas contaminadas, esta tecnologia se baseia no aquecimento direto do solo. A propagação de calor num solo é simulada matematicamente pelo fluxo acoplado de calor. Para que esta simulação seja possível é necessário a identificação dos parâmetros r

30. GEOTECHNICAL CHARACTERIZATION OF A SOFT CLAY DEPOSIT IN BAIXADA FLUMINENSE / CARACTERIZAÇÃO GEOTÉCNICA DE UM DEPÓSITO DE ARGILA MOLE DA BAIXADA FLUMINENSE
This work has focused on the geotechnical characterization of a soft clay deposit in Baixada Fluminense, Rio de Janeiro. In this area, a large embankment of approximately 500.000m2 was executed for implantation of Rio Polimeros Industry. An extensive laboratory program was carried out on undisturbed samples, extracted from the soft clay layer before embankme
