Aceleración de deslizamientos por efectos térmicos: modelación mediante el método del punto material
(2017)
Conference report
Open AccessLa 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. ... -
A constitutive model for soft clayey rocks that includes weathering effects
(Institution of Civil Engineers (http://www.ice.org.uk/), 2007)
Article
Open AccessMicrostructural 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 ... -
An undrained upper bound solution for the face stability of tunnels reinforced by micropiles
(2013)
Conference report
Restricted access - publisher's policyTunnel 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 ... -
A review of Beliche Dam
(Institution of Civil Engineers (http://www.ice.org.uk/), 2005)
Article
Open AccessBeliche 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 ... -

Caisson failure induced by wave action
(2015-08-29)
Part of book or chapter of book
Restricted access - publisher's policyIn 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 ... -
Comportamiento y estructura de suelos compactados
(2016)
Conference report
Restricted access - publisher's policyLas 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)
Conference report
Open AccessThis 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 ... -
Design of micropiles for tunnel face reinforcement: undrained upper bound solution
(2012-01)
Article
Restricted access - publisher's policyThe 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 ... -
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
Open AccessThis 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 ... -
Effect of shear band thickness on the termo-hydromechanical coupled analysis of landslides
(International Centre for Numerical Methods in Engineering (CIMNE), 2017)
Conference report
Open AccessThermal effects induced by the own motion of an unstable mass have been included in the analysis of the post-failure behavior in early works, most of them with the aim of looking for the causes of the rapid acceleration ... -
Effect of temperature induced excess pore water pressure on the shaft bearing capacity of geothermal piles
(Universitat Politècnica de Catalunya. Departament d'Enginyeria del Terreny, Cartogràfica i Geofísica, 2015-06-02)
Conference report
Open Access -
Effect of temperature induced excess porewater pressures on the shaft bearing capacity of geothermal piles
(Elsevier, 2016-12)
Article
Open AccessChanges in temperature in clays of low permeability typically induce excess porewater pressures. In the context of geothermal piles this effect has typically been overlooked since most installations have occurred in soils ... -
Excavation-induced instabilities
(CRC Press, 2019)
Part of book or chapter of book
Restricted access - publisher's policyThe aim of this chapter is to show the capabilities of MPM to simulate geotechnical problems dealing with soil excavation. The stability of supported vertical excavation in elasto-plastic material is analyzed. Results are ... -
Fast planar slides. A closed form thermo-hydro-mechanical solution
(2010)
Article
Restricted access - confidentiality agreementHeat-induced eccess pore pressures on the failure surface of a planar slide have been calculated by solving the mass and heat balance equations on the shear band. The set of differential equations and the equation of ... -
Foundation of a gravity dam on layered soft rock: shear strength of bedding planes in laboratory and large "in situ" tests
(2014-12)
Article
Restricted access - publisher's policyA 100 m high gravity dam (Castrovido dam, Burgos, Spain) is founded on a soft Weald red claystone with inter-bedded sandstone strata. Claystone weathering was identified in vertical and horizontal profiles of water content ... -
Foundation of a gravity dam on layered soft rock: shear strength of bedding planes in laboratory and large “in situ” tests
(IOS Press, 2011)
Conference report
Restricted access - publisher's policyA 100 m high gravity dam (Castrovido dam, Burgos, Spain) is founded on a soft Weald red siltstone with interbedded sandstone strata. Dam stability is essentially controlled by the available shear strength of sedimentation ... -
Highly expansive granular mixtures
(CRC Press, 2014)
Conference report
Restricted access - publisher's policyThe paper describes the behavior of mixtures of highly compacted bentonite pellets. They are considered as a suitable impervious and tight barrier for nuclear waste disposal. Laboratory experiments aimed at identifying the ... -
Incorporating a microstructural state variable in constitutive modelling
(2013)
Conference report
Restricted access - publisher's policyThe selection of constitutive variables has been extensively discussed when modeling unsaturated soils. In general, suction and degree of saturation have been involved in the definition of constitutive variables. Recently, ... -
