Hydro‐mechanically Coupled Interface Finite Element for the Modeling of Soil–Structure Interactions: Application to Offshore Constructions Open
This chapter presents how the multiphysical soil-structure interactions can be modeled using the finite element method. Hydro-mechanical couplings have become particularly important in many applications, as the loading rate and soil permea…
A First Insight on the Interaction between Desiccation Cracking and Water Transfer in a Luvisol of Belgium Open
The present paper presents the interactions between water retention/evaporation and cracking during the desiccation of intact and disturbed Belgian Luvisol. The disturbed (DS) and undisturbed (NDS) samples (reduced-tillage-residue-in (RTRI…

Constitutive modeling of chalk – application to waterflooding Open
Subsidence of chalk oil reservoirs in North Sea is related to the chalk compaction induced by fluid depletion and by the water – chalk interaction. A constitutive model is developed in order to take into account these two effects. It is ba…
Hydro-mechanical behavior of fractures: 2D, F.E.M. modeling Open
A numerical approach for modeling the coupled hydro-mechanical fracture behavior is proposed. The movement of fluids through rock fractures and consequently the evolution of their hydraulic conductivity is an important subject in many petr…
Assessing Soil Crack Dynamics and Water Evaporation during Dryings of Agricultural Soil from Reduced Tillage and Conventional Tillage Fields Open
Crack formation and development have been a general concern in agricultural science. Cracks contribute to soil aeration, aggregate formation, and easy root penetration. However, cracks accelerate soil desiccation, allow deep infiltration o…
Modelling the multiscale behaviour of claystone: deformation, rupture, and hydro-mechanical phenomena around underground galleries Open
In the context of underground exploitation, the behaviour of rocks near galleries and tunnels conditions their stability. Underground drilling generates deformations, damage, fracturing, and significant modification of flow characteristics…
Experimental and Numerical Investigation of the Drying of an Agricultural Soil Open
Due to climate change, soil desiccating became a serious concern in the agricultural area of Belgium. Knowing soil evaporation kinetic can help to elucidate and predict: the soil moisture regime, soil water retention and soil water content…
Hydro-mechanical behaviour of a pellets based bentonite seal: Numerical modelling of lab scale experiments Open
In most of the concept designs for nuclear waste disposals, bentonite-based materials are used to seal underground galleries and shafts. In order to assess the safety of such engineered barriers and to provide a good prediction for the mat…
Assessing soil crack dynamics during dryings from reduced tillage and conventional tillage fields Open
Crack formation and development has been a general concern in the agricultural science. Cracks contribute to the soil aeration, aggregate formation, and easy root penetration. However, cracks accelerated the soil desiccation, allowed deep …
Effect of desiccation cracking on the fluid transfer process in agricultural soil Open
The natural soil structure can be strongly modified and generate heterogeneities during wetting and drying processes. This significantly affects the transfer of fluids and nutrients between the atmosphere, the subsoil, the hydrosphere and …
Numerical simulation of a discontinuous gallery lining's behavior, and its interaction with rock Open
Summary Deep excavation in some geological media needs lining of the gallery. This could limit the extent of the so‐called excavation damaged zone and the resulting convergence of the material due to tunneling. Boom clay, the reference pot…
Water retention model for compacted bentonites Open
The water retention behaviour of compacted bentonites is strongly affected by multi-physical and multi-scale processes taking place in these materials. Experimental data have evidenced major effects of the material dry density, the imposed…
Water retention behaviour of compacted bentonites: experimental observations and constitutive model Open
Bentonite-based materials are studied as potential barriers for the geological disposal of radioactive waste. In this context, the hydro-mechanical behaviour of the engineered barrier is first characterized by free swelling conditions foll…

CONDITIONS FOR ELASTO-PLASTIC STRAIN LOCALIZATION IN UNSATURATED SOILS* Open
The necessary and sufficient conditions for elasto-plasic strain localization initiation in unsaturated soil massifs are proposed. Unsatu-rated behaviour is described using net stress and suction as independent stress variables and modifyi…
