A constitutive model for soft clayey rocks that includes weathering effects
(Institution of Civil Engineers (http://www.ice.org.uk/), 2007)
Article
Accés obertMicrostructural and mineralogical observations of claystones reveal the presence of clay aggregates bonded by a skeleton of inert minerals such as calcium carbonate. The behaviour of these natural materials evolves from ... -
A review of Beliche Dam
(Institution of Civil Engineers (http://www.ice.org.uk/), 2005)
Article
Accés obertBeliche Dam, a zoned earthdam with rockfill shouldersand a central clay core, experienced large collapse settlements due to reservoir impounding and direct action of rainfall. Long-term field records of vertical and ... -
A slow and complex landslide under static and seismic action
(2022-02)
Article
Accés obertA dam construction project for the heightening of a dam is threatened by a large landslide located in the Spanish Southern Pyrenees. A marked syncline structure, folding a flysch formation overlying a marl substratum, is ... -
Aceleración de deslizamientos por efectos térmicos: modelación mediante el método del punto material
(2017)
Text en actes de congrés
Accés obertLa ocurrencia de deslizamientos rápidos se ha ligado a la pérdida de resistencia efectiva a lo largo de la superficie de rotura debido a excesos de presión de agua inducidos por el calor generado durante el propio movimiento. ... -
An undrained upper bound solution for the face stability of tunnels reinforced by micropiles
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialTunnel in difficult soils may require procedures to prevent tunnel face failures. Face stabilization can be achieved by the installation of some structural elements. This paper presents an analysis of face stability of ... -

Caisson failure induced by wave action
(2015-08-29)
Capítol de llibre
Accés restringit per política de l'editorialIn 2001 a storm induced the failure of four caissons recently built for the construction of a dyke in a new entrance to the Barcelona Harbor. Understanding the failure required the analysis of the construction history and ... -
Canelles landslide: modelling rapid drawdown and fast potential sliding
(2012-03)
Article
Accés obertA 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 ... -
Compacted soil behaviour: initial state, structure and constitutive modelling
(Thomas Telford, 2013-05)
Article
Accés obertThe 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 ... -
Comportamiento y estructura de suelos compactados
(2016)
Text en actes de congrés
Accés restringit per política de l'editorialLas condiciones de compactación, definidas en la práctica por la humedad y densidad seca alcanzada, determinan el comportamiento del suelo bajo futuras cargas y trayectorias de humedecimiento y secado. En las últimas ... -
Constitutive modelling of bonded expansive geomaterials
(PRESSES DE L'ECOLE NATIONALE DES PONTS ET CHAUSSES, 2008)
Text en actes de congrés
Accés obertThis paper presents a discussion on existing approaches to derive constitutive models for bonded geomaterials conceived as composite materials. The methodology involves the partitioning of strains, the adoption of ... -
Criteria for rapid sliding I.: a review of Vaiont case
(2010-08)
Article
Accés obertVaiont 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
Accés obertThermally 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 ... -
Design of micropiles for tunnel face reinforcement: undrained upper bound solution
(2012-01)
Article
Accés restringit per política de l'editorialThe stability of tunnel faces supported by an umbrella of subhorizontal micropiles is analyzed by means of the upper bound theorem of plasticity. The micropiles are considered beams subjected to the kinematic motion imposed ... -
Design, construction, monitoring and modelling of Albagés earth dam: a case history
(Springer, 2019-05)
Article
Accés obertA zoned earth dam 40 m high is analysed and modelled using a numerical code able to deal with unsaturated–saturated soils and the coupled hydro-mechanical phenomena. The paper discusses the selection of the materials for ... -
Desplazamientos acumulados en deslizamientos inducidos por sismos mediante el método de Newmark extendido
(2022)
Text en actes de congrés
Accés oberts habitual en la práctica analizar la estabilidad de taludes y laderas afectadas por sismos mediante el método de Newmark, el cual permite estimar los desplazamientos acumulados. El método consiste en simplificar el ... -
Digital image-based analysis of a small-scale dam failure during wetting
(EDP Sciences, 2023)
Text en actes de congrés
Accés obertThe use of digital images and the correlation of them in time is commonly used in geotechnical laboratory experiments to measure surface variables in a non-invasive and massive way. Digital image correlation-based methods ... -
Dinámica de deslizamientos en rocas blandas arcillosas
(2021-07)
Article
Accés obertEl artículo analiza el comportamiento de deslizamientos en rocas caracterizadas por el predominio de su componente arcillosa y por una tipología de movimientos que se explican por el agotamiento de la resistencia al esfuerzo ... -
Discussion on “Large landslides associated with a diapiric fold in Canelles reservoir (Spanish Pyrenees): Detailed geological–geomorphological mapping, trenching and electrical resistivity imaging” by Gutiérrez et al. (2015)
(2016-06)
Article
Accés obertThis discussion a) reviews the geological model adopted for the landslide analysis and argues that there is nothing new in the reference paper, b) examines the conditions for fast catastrophic sliding and demonstrates that ... -
Dynamics of slow and fast landslides
(2020)
Text en actes de congrés
