This paper presents the results of 124 pure Mode I fracture toughness tests on two types of
anisotropic rocks, the metamorphic Grimsel Granite and the sedimentary Mont Terri …

We observed rupture growth caused by controlled fluid injections at 340‐m depth within a
fault zone in the low‐permeability Opalinus Clay in the Mont Terri Underground Research …

Abstract The Hoek-Brown (HB) failure criterion and the geological strength index (GSI) were
developed for the estimation of rock mass strength in jointed and blocky ground where rock …

We present results from an international model comparison study involving a series of
controlled fault activation experiments in Opalinus Clay at the Mont Terri Laboratory …

Guaranteeing the sealing capacity of caprocks becomes paramount as CO2 storage scales
up to the gigaton scale. A significant number of laboratory experiments have been …

Abstract The Opalinus Clay (OPA) formation is considered a suitable host rock candidate for
nuclear waste storage. However, the sealing integrity and long-term safety of OPA are …

The early understanding of the rock masses in which a mine will be constructed and
operated is of fundamental importance and required for developing reliable designs. To …

Fault reactivation due to water injection is assessed within the scope of nuclear waste
disposal design. A model using the distinct element method is applied to reproduce the fault …

Seismic events with magnitude 3 and above have been associated with the removal of rock
mass in mining environment since long-time. On the contrary, little is known about the …

Highlights The entire disturbing slope is divided into four regions. The critical sliding surface
shows an L-shaped or a W (double L)-shaped broken line. When the advancement exceeds …
