A fully coupled elastic–plastic hydromechanical model for compacted soils accounting for clay activity
(2012-01-11)
Article
Restricted access - publisher's policyA constitutive model, accounting for multiphase and multiscale coupling, is proposed for the water retention domain and the stress–strain response of compacted clayey soils. The model is based on a conceptual interpretation ... -
Ageing effects on the small-strain stiffness of a bio-treated compacted soil
(2015-09)
Article
Open AccessThe effect of ageing on the small-strain shear stiffness of compacted silty-clayey sand following a ‘soft’ biological treatment is discussed. Samples were prepared by static compaction, adding urea-degrading bacteria to ... -
Air injection tests in two argillaceous rock formations: experimental results and modelling
(CRC Press, 2016)
Conference report
Restricted access - publisher's policyAir flow through two argillaceous rock formations is investigated on the basis of laboratory work and its modelling to help in the interpretation of the results. Priority in the experimental program has been given to study ... -
An insight into the water retention properties of compacted clayey soils
(2011-04)
Article
Restricted access - publisher's policyExperimental data from different testing methodologies on different compacted clayey soils, with dominant bimodal pore size distribution, are presented and analysed, to provide a comprehensive picture of the evolution of ... -
Experimental techniques for hydromechanical and electro-chemo-hydraulic processes
(ALERT Geomaterials, 2012-10)
Part of book or chapter of book
Open AccessThis chapter presents the fundamentals behind selected experimental techniques used to control and monitor some coupled multi-physics processes. The starting point is the review of the experimental techniques for coupled ... -
Experimental techniques for multi-scale description of soil fabric and its dual pore network
(ALERT Geomaterials, 2012-10)
Part of book or chapter of book
Open AccessFabric affects many aspects of soil mechanical behaviour. When transport processes are of concern, its dual, the pore network, is the key aspect ruling the soil properties of interest. In this chapter, a review of a few ... -
Exploring fissure opening and their connectivity in a cenozoic clay during gas injection
(Springer, 2017)
Conference report
Restricted access - publisher's policyGas transport properties in argillaceous rocks are becoming an important issue within different contexts of energy-related geomechanics (disposal of radioactive waste, production of shale gas, CO2 sequestration). The present ... -
Feasibility of a soft biological improvement of natural soils used in compacted linear earth construction
(2015-02)
Article
Restricted access - publisher's policyIncreasing demand for infrastructures requires innovative, cheap and environmental sustainable practices in construction. The soils which are available on site for linear embankments often need to be improved to satisfy ... -
Gas migration in a Cenozoic clay: experimental results and numerical modelling
(Elsevier, 2016-06)
Article
Open AccessGas migration through a potential host clay formation for the geological disposal of radioactive waste in Belgium is experimentally investigated in the laboratory, and numerical modelling is performed to help in the ... -
Influence of electroosmotic treatment on the hydro-mechanical behaviour of clayey silts: preliminary experimental results
(2008)
Article
Restricted access - publisher's policyPreliminary results of an investigation focused on the influence of electrokinetic treatment on the mechanical and hydraulic behaviour of clayey soils are presented. The experimental programme aims at providing a contribution ... -
Modelling criteria for a microbiologically stabilised compacted soil in the framework of elastoplasticity.

Physical models at increasing scale and role of theoretical / numerical back-analyses
(ALERT Geomaterials, 2012-10)
Part of book or chapter of book
Open AccessIn spite of advancements in the techniques for the study of thermo-hydro-chemomechanical behaviour of geomaterials at the REV scale, the latter might not provide an exhaustive picture of transport processes in soil, when ... -
Radial stress paths in triaxial tests on compacted Boom clay: stiffness and anisotropy
(Kasetsart University, 2011)
Conference report
Restricted access - publisher's policyExperimental results of triaxial tests performed on unsaturated soil samples of statically compacted Boom clay are presented. Boom clay samples we re subjected to radial stress paths at two different constant water contents: ... -
Some remarks on the hydro-mechanical constitutive modelling of natural and compacted Boom clay.
(Taylor & Francis, 2010)
Conference lecture
Restricted access - publisher's policyNatural and compacted Boom clay have been extensively studied for their potential use as environmental barriers. In such applications, a series of coupled chemo-thermo-hydro-mechanical processes characterise the response ... -
Water retention properties of a compacted clayey silt including void ratio dependency and microstructural features
(Springer, 2012)
Conference report
Restricted access - publisher's policyAn experimental study focused on the water retention properties of a compacted clayey silt with dominant bimodal pore size distribution is reported. A water retention model accounting for soil microstructural features and ...
