Shear strength of a compacted scaly clay in variable saturation conditions

Alessio Ferrari

Scaly clays are stiff and highly fissured clays often used as construction materials. This paper presents the results of triaxial compression tests carried out on saturated and unsaturated samples of a compacted scaly clay. Complementary investigation on t ...

Modelling landslides in unsaturated slopes subjected to rainfall infiltration using material point method

Lyesse Laloui, Alessio Ferrari, Samila Sanjeevanie Bandara

This paper presents a dynamic fully coupled formulation for saturated and unsaturated soils that undergo large deformations based on material point method. Governing equations are applied to porous material while considering it as a continuum in which the ...

Characterization of THM Behaviour of Compacted MX-80 Granular Bentonite Using an Advanced Double-wall Triaxial Cell

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

This paper aims at characterization of thermo-hydro-mechanical behaviour of MX-80 granular bentonite obtained from an innovative double-cell triaxial system. The system has been mainly developed to perform suction controlled tests on unsaturated geomateria ...

Moisture and energy dynamics in fields soils

Francesco Ciocca

Soil moisture is crucial to water-cycle as it affects infiltration, runoff and land-atmosphere interactions. In dry soils the role of water vapor fluxes becomes essential and causes a tight coupling between soil moisture dynamics and heat transfer, which m ...

Hydromechanically coupled analysis of transient phenomena in a rainfall-induced landslide

Lyesse Laloui, Mathieu Nuth, John Eichenberger

Heavy rainfall can lead to shallow slips in slopes that are initially in a state of partial water saturation. Multiphysics numerical modelling approaches taking into account the involved physical key processes in variably saturated soils during rainfall ev ...

Mechanics of Unsaturated Geomaterials

Lyesse Laloui

An understanding of the mechanics of unsaturated geomaterials has become an important component of the background of a geo-engineer operating in various fields of geomechanics. Several geotechnical operations, such as compaction and excavation processes, a ...

Hydrogeochemical Modelling of Variably Saturated Soils

Laurin Wissmeier

This thesis is about the simulation of flow, transport and geochemical reactions in variably saturated soils. Motivated by the problematic disposal and revegetation of residue from aluminium refining, novel modelling tools for general geochemical reactions ...

Failure in multiphase geomaterias

Lyesse Laloui

The contributions assembled in the present volume proceed from the lectures of the 2009 ALERT Geomaterials School devoted to the Failure in the multiphase geomaterials. The multiphase behaviour of geomaterials used to be mainly considered from the point of ...

Constitutive modelling of unsaturated soils with hydro-geomechanical couplings

Mathieu Nuth

Even though the saturation in water of most natural and engineered soils is partial, constitutive models in geotechnical engineering have long made the assumption of complete saturation. The increasing knowledge of the rheological behaviour of unsaturated ...

Thermo-plasticity of fine-grained soils at various saturation states

Bertrand François

Soil is a particulate material that may undergo irreversible strain as the relative positions of the constituent particles change. That irreversible behaviour may be induced not only by an external stress variation but also by temperature or suction change ...
