An unsaturated soil is a state of the soil. All soils can be partially saturated with water.
Therefore, constitutive models for soils should ideally represent the soil behaviour over …

Variability in moisture content is a common condition in natural soils. It influences soil
properties significantly. A comprehensive understanding of the evolution of soil …

Experimental data from different testing methodologies on different compacted clayey soils,
with dominant bimodal pore size distribution, are presented and analysed, to provide a …

The creation of an excavation disturbed zone (EdZ) or excavation damaged zone (EDZ) is
expected around all man-made openings in geologic formations. Macro-and micro …

Small pores in high specific surface clay-rich caprocks give rise to high capillary entry
pressures and high viscous drag that hinder the migration of buoyant carbon dioxide CO 2 …

It is suspected that the as-compacted state of heavily compacted clays used as possible
engineered barriers for nuclear waste disposal is time dependent, and that further change …

In the context of a project for the study of the behaviour of the clay barrier in a nuclear waste
repository, the swelling properties of compacted bentonite have been investigated. Results …

Although a number of constitutive models for unsaturated soils exist in the literature, some
fundamental questions have not been fully answered. There are questions related to (i) the …

A review of the literature is initially presented to bring into light the important microstructural
effects on the hydraulic properties of different compacted clayey soils. Experimental data …

Problems related to unsaturated soils are frequently encountered in geotechnical or
environmental engineering works. In most cases, for simplicity, one can study the problems …
