Inducing tensile failure of claystone through thermal pressurization in a novel triaxial device
Philipp Braun, Pierre Delage, Siavash Ghabezloo +3
Complex coupled thermo-hydromechanical (THM) loading paths are expected to occur in clay rocks which serve as host formations for geological radioactive waste repositories. Exother…
Thermo-poro-elastic behaviour of a transversely isotropic shale: Thermal expansion and pressurization
Philipp Braun, Siavash Ghabezloo, Pierre Delage +2
The Callovo-Oxfordian (COx) claystone is considered as a candidate host rock for a deep geological radioactive waste repository in France. Due to the exothermic waste packages, the…
Transversely isotropic poroelastic behaviour of the Callovo-Oxfordian claystone: A set of stress-dependent parameters
Philipp Braun, Siavash Ghabezloo, Pierre Delage +2
In the framework of a deep geological radioactive waste disposal in France, the hydromechanical properties of the designated host rock, the Callovo-Oxfordian claystone (COx), are i…
Micromechanics analysis of thermal expansion and thermal pressurization of a hardened cement paste
Siavash Ghabezloo
The results of a macro-scale experimental study of the effect of heating on a fluid-saturated hardened cement paste are analysed using a multi-scale homogenization model. The analy…
Experimental artefacts in undrained triaxial testing
Siavash Ghabezloo, Jean Sulem
For evaluation of the undrained thermo-poro-elastic properties of saturated porous materials in conventional triaxial cells, it is important to take into account the effect of the…
Temperature induced pore fluid pressurization in geomaterials
Siavash Ghabezloo, Jean Sulem
The theoretical basis of the thermal response of the fluid-saturated porous materials in undrained condition is presented. It has been demonstrated that the thermal pressurization…
