A new column collapse apparatus for the characterisation of the flowability of granular materials
(2020-02)
Article
Restricted access - publisher's policyThe packaging industry is lacking a standard methodology to characterise the granular flow of a wide range of powders and grains in actual handling conditions. We present a new fully-instrumented granular column collapse ... -
Compacted soil behaviour: initial state, structure and constitutive modelling
(Thomas Telford, 2013-05)
Article
Open AccessThe paper explores the behaviour of compacted soils throughout the (dry density–water content) compaction plane by means of a conceptual framework that incorporates microstructural information. The engineering properties ... -
Criteria for rapid sliding I.: a review of Vaiont case
(2010-08)
Article
Open AccessVaiont slide has been represented by a model of two interacting evolutive wedges. Mass conservation during the motion implies that the upper wedge transfers mass to the lower one through an internal shearing plane. The ... -
Criteria for rapid sliding II.: thermo-hydro-mechanical and scale effects in Vaiont case
(2010-08)
Article
Open AccessThermally induced excess pore pressures have been included into a two-wedge evolutive model of Vaiont landslide. The problem requires the solution of a system of four coupled balance equations for the shear bands and the ... -
Canelles landslide: modelling rapid drawdown and fast potential sliding
(2012-03)
Article
Open AccessA large landslide (40 × 106 m3) was reactivated on the left bank of Canelles reservoir, Spain. The instability was made evident after a considerable reduction of the reservoir level. The drawdown took place during the ... -
Characterisation of the multi-scale fabric features of high plasticity clays
(Institution of Civil Engineers (ICE), 2019-12)
Article
Restricted access - publisher's policyAn investigation of the microstructural features of a high-plasticity clay, in both its natural conditions and reconstituted in the laboratory, is described. Scanning electron microscopy is used here to characterise the ... -
Landslide motion assessment including rate effects and thermal interactions: revisiting the Canelles landslide
(2019-09)
Article
Open AccessThe re-activation of a large (40 Mm3) landslide on the valley slopes of a reservoir motivated a research initiative to estimate the risk of a fast-sliding mass moving into the reservoir. A previous simplified analysis had ... -
Physical evolution of a bentonite buffer during 18 years of heating and hydration
(2020-01)
Article
Restricted access - publisher's policyThe FEBEX in situ experiment was a full-scale test reproducing the near-field of an underground nuclear waste repository. It was performed in a gallery excavated in granite, two heaters simulated the thermal effect of the ... -
Micromechanical inspection of incremental behaviour of crushable soils
(Springer, 2019-10)
Article
Open AccessIn granular soils grain crushing reduces dilatancy and stress obliquity enhances crushability. These are well-supported specimen-scale experimental observations. In principle, those observations should reflect some peculiar ... -
Thermo-hydro-mechanical coupled modeling of methane hydrate-bearing sediments: formulation and application
(2019-06)
Article
Open AccessWe present a fully coupled thermo-hydro-mechanical formulation for the simulation of sediment deformation, fluid and heat transport and fluid/solid phase transformations occurring in methane hydrate geological systems. We ... -
A stable mesh-independent approach for numerical modelling of structured soils at large strains
(Elsevier, 2019-12)
Article
Restricted access - publisher's policyWe describe the large strain implementation of an elasto-plastic model for structured soils into G-PFEM, a code developed for geotechnical simulations using the Particle Finite Element Method. The constitutive model is ... -
Induced seismicity in geologic carbon storage
(2019-06)
Article
Open AccessGeologic carbon storage, as well as other geo-energy applications, such as geothermal energy, seasonal natural gas storage and subsurface energy storage imply fluid injection and/or extraction that causes changes in rock ...
