Effect of sample disturbance in opalinus clay shales
The sample disturbance problem for different geomaterials is reviewed in this thesis. A general discussion on the disturbance sources and complexities of the disturbance problem is followed by detailed reviews on disturbance mechanisms and effects in soil and rock. This investigation leads to the …

Investigating the Influence of Mechanical anisotropy on the Fracturing Behaviour of Brittle Clay Shales with Application to Deep Geological Repositories
Clay shales are currently being assessed as possible host rock formations for the deep geological disposal of radioactive waste. However, one main concern is that the favourable long-term isolation properties of the intact rock mass could be negatively affected by the formation of an excavation …

Inherent strength and stiffness anisotropy of laminated rocks
… a shaly facies formation of bedded argillaceous Opalinus clay in an URL (FE-tunnel) to obtain the short-term stability insights. Overall, the research outcomes may have a prospective impact regarding the understanding of anisotropy of laminated, bedded and foliated rocks which improves the …

Crustal stress variability across spatial scales - examples from Canada, Northern Switzerland and a South African gold mine
… in Northern Switzerland. This location, with Opalinus clay as a host rock, is a potential repository site for high-level radioactive waste. The performed modelling aims to investigate the sensitivity of the stress tensor on tectonic shortening, topography, faults and variable rock properties …
