Modelling the multiscale behaviour of claystone: Deformation, rupture, and hydro-mechanical phenomena around underground galleries

In the context of underground exploitation, the behaviour of rocks near galleries and tunnels conditions their stability. Underground drilling generates deformations, damage, fracturing, and significant modification of flow characteristics in the surrounding rock. However, the influence of small-scale characteristics and behaviour on the rock...

Microstructural effects on strain localization in a multiscale model for hydro-mechanical coupling

Modelling the excavation damaged zone using a hydro-mechanical double-scale model

The principle of deep geological repositories for the disposal of radioactive waste relies among others on the low permeability of the host rock. As the permeability is influenced by mechanical damage of the material, the coupling between hydraulic and mechanical behaviour of the host rock is of importance in the study of radioactive waste...

Modelling the excavation damaged zone using a hydro-mechanical double-scale model

Disposal of spent nuclear fuel and long lived radioactive waste in deep clay geological formations is one of the promising options worldwide. In this concept of the geological disposal system, the Boom Clay is considered as a potential host rock when designing a generic waste repository in the Netherlands. For design and evaluation of a...
