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...
After a short period of relatively intense rainfall, a deep-seated landslide occurred in a slope in Rio de Janeiro.
On the following day, field inspection revealed full saturation of the failure mass, despite the inexistence of groundwater in
the slope. A comprehensive experimental investigation was undertaken to determine the ge...
The Brazilian road network is constructed in a highly heterogeneous geological environment and some stretches
cross through discontinuous rock masses that have uncertain or even ignored geotechnical characteristics. Rock slopes are
potentially unstable surfaces and as such are susceptible to rockfalls that affect the highway&...
This paper reviews the behavior of three types of piles (bored, CFA and Omega piles), installed in the experimental site
of Unicamp (State University of Campinas). Unicamp subsoil is characterized by non-saturated diabasic soil, lateritic in its
surface layer. Extensive data from geotechnical investigation is presented, expressed...
