Sustainable Remediation: A New Way of Thinking the Contaminated Sites Management

January 29, 2020

Within the evolution in the remediation field, the traditional approach to contaminated sites management, based almost exclusively on the risk, time, cost, and decontamination efficiency, is gradually being replaced by the concepts of sustainability. The most recent focus is the incorporation of the term “sustainable remediation (SR)&rdquo...

Effects of Hydraulic Gradient Variation on the Structure and Strength of a Compacted Tropical Soil

May 26, 2020
Tropical soils have been extensively studied to evaluate the technical feasibility of their application in hydraulic earthworks such as compacted clay barriers in landfills. In these earthworks, the water flow in the porous medium generates percolation forces that can promote structural changes in the soil, with possible deleterious repercussions on its mechanic...

Tunnel Misalignment with Geostatic Principal Stress Directions in Anisotropic Rock Masses

February 13, 2020
Rock masses may present pronounced stress anisotropy, and so it is likely that a tunnel is misaligned with the geostatic principal stress directions. As a consequence, anti-symmetric axial displacements and axial shear stresses are induced around the tunnel due to the presence of far-field axial shear stresses. Limited research has been conducted on the effects ...

Physicochemical Modifications in Geomaterials and Their Leachates Extracted from Acidic Attack

April 17, 2020
Exposure of geomaterials to acid leachates may cause chemical species desorption, mineral dissolution, and metal leaching. This study seeks to understand the changes in the physicochemical composition of liquid extracts resulting from the exposure of four different geomaterials (uniform fine sand, basalt residual soil, kaolin, and bentonite) to a blank solution ...
