AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Sand/bentonite (S/B) mixtures are considered as backfilling materials for nuclear waste storage. The paper presents an experimental campaign that was carried out to investigate the swelling behavior of a S/B mixture, under different hydro-chemo-mechanical ...
Elastic properties of gas shales are of utmost importance for the exploitation of shale gas reservoirs. Static elastic properties are usually measured by performing unloading-reloading cycles in uniaxial or triaxial compressive tests. The response of gas s ...
Retaining structures often interact with soils in unsaturated conditions and their performance is influenced by environmental actions. Currently, geotechnical analysis and design approaches mainly consider the soils either totally dry or totally saturated. ...
This paper investigates the anisotropic hydro-mechanical behaviour of Opalinus Clay shale, the host material currently being considered for the construction of a nuclear waste repository in Switzerland. Consolidated and drained triaxial tests on Opalinus C ...
Sustained load actions are permanently present in concrete structures, as for example self-weight and dead loads on bridges or soil pressure on cut-and-cover tunnels. These actions may increase throughout a structure's lifetime, for instance after refurbis ...
The frequency dependence of seismic properties of fully saturated rocks can be related to wave-induced fluid flows at different scales. The elastic dispersion and attenuation of four fluid-saturated carbonate rocks, with different microstructures, have bee ...
Shales are involved in energy-related applications such as the extraction of shale gas, the CO2 storage and the nuclear waste disposal. In these contexts, fundamental issues come along with the multiphysical conditions in which shales are found, where mech ...
Seismic assessment of unreinforced masonry structures remains a challenge. This dissertation investigates the in-plane behavior of historical masonry elements and proposes an advanced simulation method based on the cohesive zone model (CZM) in a finite ele ...
We investigate the effect of shear dilatancy of a permeable fault on the diffusion of pore pressure and the occurrence of dynamic slip. Starting from the results of Garagash & Germanovich (2012), we include the effect of both inelastic changes of material ...
Over the last decades, a large understanding has been gained on the elastic properties of rocks. Rocks are, however, porous materials, which properties depend on both response of the bulk material and of the pores. Because in that case both the applied ext ...
