The Opalinus Clay is a potential host rock for radioactive waste repositories. Triaxial tests at different load levels and directions carried out on Opalinus clay showed that the mechanical behaviour of this soft rock is anisotropic. The stiffer samples ar ...
This thesis is about the simulation of flow, transport and geochemical reactions in variably saturated soils. Motivated by the problematic disposal and revegetation of residue from aluminium refining, novel modelling tools for general geochemical reactions ...
In a few years, safe and definitive solutions should be ready to manage large quantities of high-level radioactive waste. Deep geological repository involving a multibarrier system constitutes one of the most promising options to isolate such waste from th ...

In a few years, safe and definitive solutions should be ready to manage large quantities of high-level radioactive waste. Deep geological repository involving a multi-barrier system constitutes one of the most promising options to isolate such waste from t ...
A numerical model for a prechamber autoignition gas engine under development has been established based on an experimental test case. With a simplified finiterate/ eddy-dissipation model for the combustion of natural gas, it was possible to properly reprod ...
Using advanced hydro-geological and geo-mechanical finite element simulations, it has been possible to model the behavior of a large slope movement, namely the La Frasse landslide in Switzerland. The slide experiences a permanent movement of about 10 to 15 ...
Soil is a particulate material that may undergo irreversible strain as the relative positions of the constituent particles change. That irreversible behaviour may be induced not only by an external stress variation but also by temperature or suction change ...
With the development of numerical tools used to simulate fluid-structure interactions phenomena, investigations on hydrodynamic damping are now more accessible and the studied cases are more flexible. The aim of the present study is, at first, to analyze t ...
An understanding of the mechanics of unsaturated geomaterials has become an important component of the background of a geo-engineer operating in various fields of geomechanics. Several geotechnical operations, such as compaction and excavation processes, a ...
The contributions assembled in the present volume proceed from the lectures of the 2009 ALERT Geomaterials School devoted to the Failure in the multiphase geomaterials. The multiphase behaviour of geomaterials used to be mainly considered from the point of ...
