Water retention behavior of deformable soils-experiment and modeling

Lyesse Laloui, Alessio Ferrari, Mathieu Nuth, Simon Salager

The paper presents an experimental and modelling approach for the soil water retention behaviour of two deformable soils. The objective is to investigate the physical mechanisms that govern the soil water retention properties and to propose a constitutive ...

An investigation into the water retention behaviour of deformable soils

Lyesse Laloui, Alessio Ferrari, Mathieu Nuth, Simon Salager

This paper aims to analyse the anisotropic features of behaviour of Opalinus Clay using the theory of plastic multi-mechanisms. The results of triaxial tests conducted with different load levels and directions showed that the mechanical behaviour of this s ...

Modeling the Onset of Shallow Landslides in Partially Saturated Slopes Subjected to Rain Infiltration

Lyesse Laloui, Mathieu Nuth, John Eichenberger

Heavy rainfall can lead to shallow slips on slopes which are often initially in a state of partial water saturation. A multiphysics approach and advanced constitutive modeling are necessary to take into account the physical key processes in partially satur ...

Benchmarking of constitutive models for unsaturated soils

Lyesse Laloui, Mathieu Nuth

The paper presents a collaborative piece of research undertaken by seven research teams from different universities within the ‘Mechanics of Unsaturated Soils for Engineering’ (MUSE) network. The objective is to benchmark different approaches to constituti ...

A model for the water retention behavior of deformable soils including capillary hysteresis

Lyesse Laloui, Mathieu Nuth

Experimental findings on the hysteresis of the soil water retention curve, relating the degree of saturation to the matric suction, have to be superimposed with the aspects due to the soil matrix deformation. In order to set a comprehensive model for the r ...

Analysis of the compaction phenomena due to the water injection in reservoirs with a three-phase geomechanical model

Lyesse Laloui, Mathieu Nuth

In the coastal regions, the land subsidence due to the industrial pumping of underground fluids such as methane is documented by the means of in situ surveys. The laboratory characterization of the gas bearing formations has also been published, which comp ...

Investigations on water retention behaviour of deformable soils

Lyesse Laloui, Alessio Ferrari, Mathieu Nuth, Simon Salager

The trend in modern unsaturated soil mechanics is to enhance the physical understanding of the soil water retention properties. It is agreed that the retention characteristics depend on the state of compaction and are related to the deformability of the me ...

Anisotropic mechanical response of a shale

Lyesse Laloui, Mathieu Nuth, Simon Salager

The purpose of the study is to characterize the main features of the anisotropic mechanical behaviour of a shale (Opalinus Clay), and to identify an anisotropic constitutive framework adapted to the response of the material under mechanical perturbations. ...
