New Techniques on Soft Soils

practically oriented reference volume on soft soil engineering contains case studies of soft soil techniques from all over the world New Techniques on Soft Soils covers a wide range of updated techniques related to site investigation, vertical drains, surcharge, piled embankment, granular piles, deep mixing, monitoring and performance. An essential reference for designers and practitioners involved in soft soil construction, it provides a comprehensive view of current experiences and opinions of researchers and professionals from different parts of the world involving site investigation, design and construction on soft clays. This book presents a collection of selected expert contributions on innovations in soft soil engineering, that were presented at the Symposium on New Techniques for Design and Construction in Soft Clays held in Guarujá, Brazil, on 22 and 23 May 2010.

Márcio Almeida earned his Civil Engineering degree at the Federal University of Rio de Janeiro, in 1974 and obtained his MSc at COPPE/UFRJ in 1977 when he joined COPPE as Assistant Lecturer. Marcio got his PhD from the University of Cambridge, UK in 1984. Then he returned to UFRJ and in 1994 became Professor of GeotechnicalEngineering. His postdocs were in Italy (ISMES) and at NGI, Norway in the early 1990s and he was also visiting researcher at the universities of Oxford, Western Australia and ETH, Zurich. He is currently one of the leading researchers of the National Institute of Science and Technology – Rehabilitation of Slopes and Plains (INCT-REAGEO). He has been the Director of COPPE’s MBA “Post-Graduate Program in Environment’’ since 1998. He has published numerous articles in journals and conferences in Brazil and abroad and has supervised over 60 doctoral and master dissertations. He received the Terzaghi and Jose Machado awards from the Brazilian Association of Soil Mechanics and Geotechnical Engineering (ABMS). His experience ranges from soft clay engineering, environmental and marine geotechnics tosite investigation, physical and numerical modeling as well as extensive experience in geotechnical consulting.
