1. Physical and geometric non-linear analysis using the finite difference method for one-dimensional consolidation problem
Abstract This article presents a numerical model based on the finite difference method for the physical and geometric non-linear analysis of a one-dimensional consolidation problem regarding a saturated, homogeneous and isotropic soil layer with low permeability and high compressibility. The problem is formulated by adopting the void ratio as the primary var

2. Reversibility of the Hardening Process of Plinthite and Petroplinthite in Soils of the Araguaia River Floodplain under Different Treatments
ABSTRACT Although ferruginous materials occur frequently in soils of tropical regions, information about the reversal of the hardening process of these materials is scarce. This study assessed the influence of different chemical treatments and periods of immersion on the reversibility of the hardening process of plinthite and petroplinthite in soils of the A

3. Comportamento hidráulico de um perfil de solo não saturado de Aparecida de Goiânia-GO / Hydraulic behavior of an unsaturated soil profile of Aparecida de Goiania-GO
The hydraulic behavior of a tropical and unsaturated soil profile of Aparecida de Goiânia-GO is presented. The main objective of this research was to contribute to the understanding of hydraulic properties of a tropical soil, with special emphasis on the soil-water characteristic curves and its hysteresis. The research work done was divided into two main pa

4. Análise da interação solo-estrutura via acoplamento MEC-MEF / Analysis of soil-structure interaction using BEM-FEM coupling
O objetivo central deste trabalho é o estudo da interação do solo com a estrutura. Para tanto, são introduzidos mais recursos na ferramenta numérica desenvolvida no trabalho de Almeida (2003a). O solo é modelado pelo método dos elementos de contorno (MEC) tridimensional, aplicando a solução fundamental de Kelvin. É possível analisar problemas nos

5. Microemulsões a base de óleos vegetais: formação, propriedades e emprego na descontaminação EX-SITU de Solo / Vegetable oil-based microemulsions: formation, properties and application for "exsitu" soil decontamination
In the present project, we were interested in assessing the use of Brazilian vegetable oils in the "ex-situ" decontamination of soils from polycyclic aromatic hydrocarbons (PAHs). In this process, contaminated soil is treated with a microemulsion (µE) composed of water (W) /commercial non-ionic surfactant (S) C9/11EO4 /oil (O). The latter term refers to the
