Formulation for the THMC analysis of clayey materials: application to radioactive waste disposal
(American Society of Civil Engineers (ASCE), 2008)
Text en actes de congrés
Accés restringit per política de l'editorialA fully coupled formulation combining reactive transport and an existing thermo-hydro-mechanical (THM) code is briefly described. Special attention has been given to phenomena likely to be encountered in clay barriers used ... -
Fully coupled thermo-hydro-mechanical double-porosity formulation for unsaturated soils
(2016-12)
Article
Accés obertThis work presents a fully coupled formulation developed to handle engineering problems in unsaturated (and saturated) soils that present two dominant void levels. The proposed framework assumes the presence of two porous ... -
Gas flow through clay barriers
(2008-04)
Article
Accés obertA model for the simulation of gas flow in clayey rocks and clays is described. Gas migration is associated with the development of preferential paths along existing or pressure-dependent discontinuities. The model handles ... -

Gas migration in sand/bentonite mixtures through preferential paths
(2011)
Text en actes de congrés
Accés restringit per política de l'editorialSand/bentonite mixtures are considered as buffer material in low and medium radioactive waste disposal schemes. While the bentonite provides low permeability and swelling capacity, the sand is intended to improve mechanical ... -
Geomechanical response of fractured reservoirs
(2018-12)
Article
Accés obertGeologic carbon storage will most likely be feasible only if carbon dioxide (CO2) is utilized for improved oil recovery (IOR). The majority of carbonate reservoirs that bear hydrocarbons are fractured. Thus, the geomechanical ... -
Geomechanical stability of the caprock during CO2 sequestration in deep saline aquifers
(2011)
Article
Accés obertSequestration of carbon dioxide (CO2) in deep saline aquifers has emerged as a mitigation strategy for reducing greenhouse gas emissions to the atmosphere. The large amounts of supercritical CO2 that need to be injected ... -

Heat storage efficiency, ground surface uplift and thermo-hydro-mechanical phenomena for high-temperature aquifer thermal energy storage
(2022-10)
Article
Accés obertHigh-temperature aquifer thermal energy storage (HT-ATES) systems can help in balancing energy demand and supply for better use of infrastructures and resources. The aim of these systems is to store high amounts of heat ... -
Hydro-chemical modelling of in situ behaviour of bituminized radioactive waste in Boom Clay
(2014-06)
Article
Accés obertThe hydro-chemical (CH) interaction between swelling Eurobitum bituminized radioactive waste (BW) and Boom Clay was investigated to assess the feasibility of geological disposal for the long-term management of this waste. ... -
Hydro-chemo-mechanical modelling of tunnels in sulfated rocks
(Thomas Telford, 2017-11)
Article
Accés obertA modelling procedure to address the tunnel–anhydritic rock interaction is described in this paper. The model incorporates the basic physico-chemical phenomena involved in rock swelling, often observed during excavation ... -
Hydro-mechanical modelling and analysis of multi-stage tunnel excavations using a smoothed excavation method
(Elsevier, 2021-07)
Article
Accés obertThe main objective of this article is to provide a general numerical approach for the hydro-mechanical (HM) modelling of tunnels excavated in saturated rock masses exhibiting plastic behaviour, considering a multi-stage ... -
Impacts of cold CO2 injection in deep saline aquifers on the rock mechanical integrity.
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialInjecting CO2 into aquifers at depths greater than 800 m brings CO2 to a supercritical state where its density is large enough to ensure an efficient use of pore space. However, CO2 may not be in thermal equilibrium with ... -
Induced seismicity in geologic carbon storage
(2019-06)
Article
Accés obertGeologic carbon storage, as well as other geo-energy applications, such as geothermal energy, seasonal natural gas storage and subsurface energy storage imply fluid injection and/or extraction that causes changes in rock ... -
Influence of numerical model mesh properties on predicted in soil temperature, relative humidity and degree of saturation of reinforced soil structures
(2022)
Comunicació de congrés
Accés restringit per política de l'editorialGeosynthetic materials are routinely used in soil reinforcement and stabilization applications. They have proven to be an important part of the sustainable solution for reinforced soil walls (RSWs). For RSW constructed ... -
Influence of suction on the mechanical behaviour of rock joints under shear loading

Is the degree of saturation a good candidate for Bishop’s X parameter?
(CRC Press, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialIn unsaturated soil mechanics, the quest for an effective stress playing the same role as Terzaghi’s effective stress does for saturated soils has introduced a long standing debate, dating back to the 1960s. Several ... -
