With the advent of modern microstructural testing techniques and microstructure based
constitutive models the microstructural characterisation of soils is gaining prominence. This …

Bentonite-based materials have been considered in many countries as engineered
barrier/backfilling materials in deep geological disposal of high-level radioactive waste …

Unsaturated soil mechanics has rapidly become a part of geotechnical engineering practice
as a result of solutions that have emerged to a number of key problems (or challenges). The …

In order to study the hydro-mechanical behaviour of highly compacted unsaturated clays
used in engineered clay barriers for nuclear waste disposal, some experimental techniques …

The paper describes a three-phase single-point material point method formulation of
coupled flow (water and air) for hydro-mechanical analysis of geotechnical problems …

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 …

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 …

Analytical and comprehensive, this state-of-the-art book, examines the mechanics and
engineering of unsaturated soils, as well as explaining the laboratory and field testing and …

Compacted bentonite-based materials are often used as buffer materials in radioactive
waste disposal. A good understanding of their hydro-mechanical behaviour is essential to …

The influence of fabric on mechanical behaviour is explicitly considered in some of the
current constitutive models for unsaturated soils. These are based on assumptions …
