Experimental and numerical analysis of the unsaturated soil shrinkage and swelling behaviour under different compaction conditions
Abdallah Najdi
Abstract:(English) The thesis presents part of an ongoing nvestigation on the Thermo-Hydro-Mechanical (THM) behaviour and cracking of deformable unsaturated soils undergoing cycles of drying and wetting. An experimental approach was first adopted to understand the principal mechanisms of the THM behaviour. A main principal variable is the negative porewater pressure (suction). Suction is an essential component for the constitutive relations. Direct measurements at high suction range is only possible to this date using … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
