Evolution of water content and suction of Opalinus Clay from recovery at the drilling site to handling in the laboratory
Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo
Advanced geotechnical engineering applications, such as shale gas extraction, CO2 geological sequestration, and geological radioactive waste storage, often involve various types of shales located at significant depths. Shales exhibit mechanical properties ...
Oxford2024Insights from an extensive triaxial testing campaign on a shale for comparative site characterization of a deep geological repository
Lyesse Laloui, Alessio Ferrari, Eleonora Crisci
Several boreholes were drilled for site comparison of a deep geological repository (DGR) in Northern Switzerland. The main target of the exploration program was the >100m thick Opalinus Clay, the designated host rock encountered at approximately 450 to 100 ...
Amsterdam2024Thermo-hydro-mechanical analysis of the complete lifetime of the bentonite barrier in the FEBEX in-situ test
Lyesse Laloui, Alessio Ferrari, Jose Antonio Bosch Llufriu, Yafei Qiao
The FEBEX test was a large-scale demonstration project for the deep geological disposal concept of nuclear waste involving bentonite seals that lasted 18 years. One of the objectives of the test was to evaluate the capabilities of numerical methods to prov ...
2023Hydro-mechanichal characterisation of bentonite/steel interfaces
Alessio Ferrari, Eleni Stavropoulou, Fabiana Sannasardo
The hydromechanical response of a Wyoming-type bentonite (MX-80) and its interface with steel was studied in terms of shear resistance under different hydration levels. A series of shear tests under constant normal stress were performed in total suction co ...
2023Shear strength and shear stiffness analysis of compacted Wyoming-type bentonite
Wyoming-type bentonite is one of the materials to be used as part of the Engineered Barrier System (EBS) in deep geological disposal facilities for the safe disposal of spent nuclear fuel.In the KBS-3 type repository, the canisters containing the spent fue ...
ELSEVIER2023Pore-pressure coefficients for unsaturated soils: generalized effective stress approach
Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo
Geotechnical problems with total stress changes occurring rapidly relative to the soil consolidation time can be conveniently addressed using an effective stress-based approach. For saturated states, analytical formulations of pore-pressure coefficients ad ...
CANADIAN SCIENCE PUBLISHING2023Experimental and Numerical Investigation on Water Exchange of Opalinus Clay Samples
Alessio Ferrari, Eleni Stavropoulou, Qazim Llabjani, Vincenzo Sergio Vespo
Opalinus Clay is a fine-grained sedimentary geomaterial with a mineral composition consisting mainly of silicates, carbonates and quartz. Due to its favourable barrier properties, this geomaterial has been selected as the host rock for the underground disp ...
Wei Wu, Universität für Bodenkultur2023Hydro-Mechanical Characterization of a Shale by Unusually High-Pressure Oedometric Tests
Alessio Ferrari, Eleonora Crisci
The note presents selected results of an experimental campaign conducted with the aim to investigate the hydro-mechanical behaviour of a shale recovered at a depth of about 900 m below the ground. High-pressure oedometric tests were performed to investigat ...
Wei Wu, Universität für Bodenkultur2023On Multiphysical Couplings in Energy Geotechnics: Relevance and Applications
Energy Geotechnics includes several applications related to the recovery and storage of energy from and into the ground, energy transportation, and the management of waste and carbon dioxide generated from energy use. These applications often involve the n ...
Wei Wu, Universität für Bodenkultur2023On the Fabric of a 3D Printed Soil
3D printing of earthen materials is on the rise in the field of Additive Manufacturing (AM) due to the opportunity this technique offers to realize structures and manufacts with low environmental impacts, but very little is known about the hydromechanical ...
