Physical characterization of fault rocks within the Opalinus Clay formation

Marie Estelle Solange Violay, Christophe Nussbaum, Luis Felipe Orellana Espinoza

Near-surface disposal of radioactive waste in shales is a promising option to safeguard the population and environment. However, natural faults intersecting these geological formations can potentially affect the long-term isolation of the repositories. Thi ...

Frictional Properties of Opalinus Clay

Marie Estelle Solange Violay, Luis Felipe Orellana Espinoza

Opalinus Clay (OPA) is the host rock being proposed in Switzerland for disposal of high-level radioactive waste. The stability of fault zones within this formation is a key issue to ensure long-term performance of the repository. To understand the friction ...

On the stability of clay-bearing faults

Marie Estelle Solange Violay, Luis Felipe Orellana Espinoza

Opalinus clay (OPA) is shale rock studied under the context of deep geological disposal by The Mont Terri Laboratory research program in Switzerland. Despite its favorable hydro-mechanical properties, the presence of a large tectonic fault system intersect ...

Predicting the axial capacity of piles in sand

Lyesse Laloui, Jean-Marie Fuerbringer, Alessandro Francesco Rotta Loria, Alberto Minardi, Luis Felipe Orellana Espinoza

Currently, although several tools have been proposed for the numerical modelling of the pile-soil interface, there is not a well-established framework concerning the quantitative impact that different estimations of the mechanical properties of this settin ...
