Insights 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 ...
Amsterdam2024Estimation of the bar stress based on crack width measurements in reinforced concrete structures
Estimating the stress of reinforcing bars and its variations in service conditions can be useful to determine the reserve capacity of structures or to assess the risk of fatigue in the reinforcement. This paper investigates the use crack width measurements ...
Ernst & Sohn2024Energy geotechnology: A new era for geotechnical engineering practice
Energy geotechnology provides low carbon, cost-effective and local energy solu-tions to structures and infrastructures, which opens a new era for the geotechnical engineering practice, by extending the conventional role of structural design to the ...
CRC Press2023On the Post-peak Behaviour of Remoulded and Jointed Clay Samples During Triaxial Compression Tests
The note presents a selection of the results of a large experimental program conducted with the aim of characterizing the shear strength of Opalinus Clay and Speswhite Kaolin in remoulded and reconstituted conditions, through the execution of unconventiona ...
2023Pore-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 PUBLISHING2023Hydro-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 Bodenkultur2023Investigation of the effect of mineral dissolution on the geomechanical behaviour of geomaterials
Geotechnical engineering scenarios engaged in internal erosion or mineral dissolution were found worldwide, from CO2 sequestration projects to internal erosion of earth dams. Materials subjected to loss of solid phase from their internal fabric vary from s ...
EPFL2022Influence of depositional fabric on mechanical properties of naturally deposited sands
Fabric characteristics and shear deformation behaviour were analysed in four intact small-scale samples, including two disturbed and two undisturbed samples of naturally deposited sand from a shoal in the San Francisco Bay. Triaxial compression tests were ...
