ADVANCES IN UNSATURATED SOILS
Berardo Caicedo,Carol Murillo,Laureano Hoyos,Julio Esteban Colmenares
New theories and testing techniques related with Unsaturated Soil Mechanics have proven to be valuable tools to study a broad spectrum of geo-materials which includes rocks, rock fills, frozen soils and domiciliary solid wastes. These new theories and testing techniques have permitted the analysis of several traditional problems from a new perspective (e.g., swelling or collapsible soils and compacted soils or pavements materials), and they have also shown their efficiency to study new energy-related problems like CO2 sequestration and nuclear waste disposal.
Advances in Unsaturated Soils is a collection of papers from the 1st Pan-American Conference on Unsaturated Soils organized in Cartagena de Indias, Colombia,
in February 2013. The volume includes 76 research papers coming for all over the world, as well as 7 keynotes papers by well known international researchers. The contributions present a variety of topics including:
• Advances in testing techniques
• Unsaturated soil behavior
• Constitutive modeling and microstructure
• Numerical modeling
• Geotechnical problemsAdvances in Unsaturated Soils
is expected to become a useful reference to academics and professionals involved in Unsaturated Soil Mechanics.
