Experimental analysis of the cyclic behaviour of Kaolin at high temperature

This paper presents the results of an experimental study related to the thermal effects on kaolin clay cyclic mobility. The thermal effects were identified by comparing the experimental results of cyclic triaxial tests performed at high temperature (90 C) ...

Hydro-mechanical modelling of a natural slope affected by a multiple slip surface failure mechanism

Lyesse Laloui, Alessio Ferrari

A coupled hydro-mechanical formulation is presented for the analysis of landslide motion during crisis episodes. The mathematical formulation is used to model a natural slope affected by a multiple slip surface failure mechanism, in which pore water pressu ...

Geomechanical modeling of the Steinernase landslide (Switzerland)

Lyesse Laloui, Alessio Ferrari

A geomechanical model was developed to analyse the behaviour of a natural slope located on the bank of the Rhine River between the towns of Stein and Mumpf in Switzerland. The slope is affected by a landslide and three strategic infrastructure assets are l ...

Geomechanical modelling of a natural slope affected by a multiple slip surface failure mechanism

Lyesse Laloui, Alessio Ferrari

This paper presents a geomechanical model that was developed to investigate the behaviour of a natural slope located on the bank of the Rhine between the towns of Stein and Mumpf in Switzerland. The slope, affected by a large landslide, constitutes a relev ...

Constitutive modelling of unsaturated soils with hydro-geomechanical couplings

Mathieu Nuth

Even though the saturation in water of most natural and engineered soils is partial, constitutive models in geotechnical engineering have long made the assumption of complete saturation. The increasing knowledge of the rheological behaviour of unsaturated ...

Differences in experiences in rockfall hazard mapping in Switzerland and Principality of Andorra

Vincent Labiouse, Jacopo Maria Abbruzzese

The need to cope with rockfall hazard and risk led many countries to adopt proper strategies for hazard mapping and risk management, based on their own social and political constraints. The experience of every single country in facing this challenge provid ...

GEOMECHANICS OF STRUCTURED MATERIALS

Lyesse Laloui

Natural soils and rocks are usually structured at various levels starting from the scale of the particles, pores and their networks up to the field scale. The particular structure in these materials, as often represented by the combination of fabric and bo ...

Geological characterization of cataclastic rock samples using medical X-ray computerized tomography

Pierre Guillaume Christe

Technical difficulties associated with tunnelling operations in tectonized geological settings are frequently encountered. They may include instantaneous and delayed cavity convergence, sudden collapse of walls or roof of a gallery, outpouring of fault-fil ...

Use of Orbital Shaken Disposable Bioreactors for Mammalian Cell Cultures from the Milliliter-Scale to the 1,000-Liter Scale

Alfio Quarteroni, Florian Maria Wurm, David Hacker, Mathieu Benjamin Stettler, Xi Zhang

Driven by the commercial success of recombinant biopharmaceuticals, there is an increasing demand for novel mammalian cell culture bioreactor systems for the rapid production of biologicals that require mammalian protein processing. Recently, orbitally sha ...

Study of a progressive failure in soil using BEDS

Luc Thévenaz, Stella Foaleng Mafang

In Geotechnical Engineering, progressive failure in soil-structure interaction is one of the least understood problems. It is difficult to study this phenomenon at laboratory scale, because of the large amount of strain gages required per unit length/area ...
