The use of prefabricated vertical drains with vacuum preloading and surcharge preloading is now common practice and is proving to be one of the most effective ground improvement techniques known. The factors affecting its performance, such as the smear zone, the drain influence zone, and drain unsaturation, are discussed in this paper. In order to evalu...
View ArticleThis work studied the transport phenomena in the soil of the Gramacho MSW landfill located in Rio de Janeiro,
Brazil. A model was proposed to determine the mass transfer rate of the leachate contaminant ions to the soil particles.
Previous researchers have focused on the diffusion and sorption phenomena using simple relations tha...
The use of Permeable Reactive Barriers (PRBs) for in situ remediation of contaminated groundwater represents
an attractive technology for both economic and operational reasons. A reactive medium widely used in PRBs is the
Zero-Valent Iron (ZVI) which, in several case studies, has proved highly efficient for the removal of both in...
Geotechnical design is based on site investigations which provide a reasonable overview of the soil profile and a
realistic estimate of the geotechnical properties of each component layer. Nevertheless, when centrifuge modelling is involved, in
situ tests become an additional challenge mainly because of limitations of in-flight p...
