Modelling a hydration and heating column test on unsaturated bentonite using a double-porosity approach
(EDP Sciences, 2023)
Article
Accés obertA controlled re-saturation of a heated 50 cm long column made of MX-80 bentonite pellets in the CIEMAT laboratory facilities (Madrid, Spain) has been running for 10 years (2011-2021). The experimental data on the saturation ... -
Modelling methane hydrate saturation in pores: capillary inhibition effects
(2021-09)
Article
Accés obertExperimental and field observations evidence the effects of capillarity in narrow pores on inhibiting the thermodynamic stability of gas hydrates and controlling their saturation. Thus, precise estimates of the gas hydrate ... -
Modelling of a deep excavation in a stiff clay
(2009)
Text en actes de congrés
Accés obertThis extended abstract presents an interpretation of the response of a mudstone during the excavation of a shaft at high depths (500m). Instrument layout and numerical model are described. A very good agreement is observed ... -
Modelling soil-vegetation-atmosphere in a field experiment
(2023)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper, a soil-atmosphere-vegetation interaction, comprised of the state of the atmosphere and its interactions with vegetation in terms of precipitation, wind, temperature, and radiation, is used based on a Finite ... -
Modelling the mechanical behaviour of Callovo-Oxfordian argillite: formulation and application
(Springer, 2017)
Text en actes de congrés
Accés restringit per política de l'editorialThe paper presents a constitutive model for argillaceous rocks, developed within the framework of elastoplasticity, that includes a number of features that are relevant for a satisfactory description of their hydromechanical ... -
Modelling the mechanical behaviour of expansive clays
(Elsevier, 1999)
Article
Accés obertA simple formalism is presented to model the behaviour of expansive clays. Two levels of structure are considered. The behaviour of the macrostructure follows the model developed for unsaturated materials by Alonso et ... -
Monitoring of a full-scale embankment experiment regarding soil–vegetation–atmosphere interactions
(2018-06)
Article
Accés obertSlope mass-wasting like shallow slides are mostly triggered by climate effects, such as rainfall, and soil–vegetation–atmosphere (SVA) interactions play a key role. SVA interactions are studied by a full-scale embankment ... -
Monitoring the role of soil hydrologic conditions and rainfall for the triggering of torrential flows in the Rebaixader catchment (Central Pyrenees, Spain)
(2023-02)
Article
Accés obertTorrential flows (debris flows and debris floods) are mainly triggered by precipitation and soil hydrological processes. Most early warning systems in torrential catchments are rainfall-based. However, this approach can ... -
Nonlocal plasticity modelling of strain localisation in stiff clays
(Elsevier, 2018-11)
Article
Accés obertThe paper addresses the numerical simulation of strain localisation in stiff clays that exhibit softening behaviour. An elastoplastic constitutive model developed to incorporate key features of stiff clay behaviour is ... -
Numerical modelling of slope–vegetation–atmosphere interaction: an overview
(2017-08)
Article
Accés obertThe behaviour of natural and artificial slopes is controlled by their thermo-hydro-mechanical conditions and by soil–vegetation–atmosphere interaction. Porewater pressure changes within a slope related to variable ... -
