Physical characterization of fault rocks within the Opalinus Clay formation

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

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 ...

Variations in elastic and electrical properties of crustal rocks with varying degree of microfracturation

Marie Estelle Solange Violay, Lucas Xan Pimienta, Luis Felipe Orellana Espinoza

This work aims at investigating the effect of varying degrees of microfracturing on the joint elastic and electrical transport properties of rocks. Different crustal rocks were subjected to Thermal Treatment, expected to induce microfracturing, up to diffe ...

Frictional and transport properties of faults zones in the Opalinus Clay formation

Luis Felipe Orellana Espinoza

Deep geological repositories in clay formations are a promising option to ensure the long-term isolation of nuclear waste from the population and the environment. In Switzerland, the Opalinus Clay (OPA) formation is a shale whose favorable barrier properti ...

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 ...
