Foundation of a gravity dam on layered soft rock: shear strength of bedding planes in laboratory and large "in situ" tests
(2014-12)
Article
Accés restringit per política de l'editorialA 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)
Text en actes de congrés
Accés restringit per política de l'editorialA 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 ... -
Gas flow through clay barriers
(2008-04)
Article
Accés obertA model for the simulation of gas flow in clayey rocks and clays is described. Gas migration is associated with the development of preferential paths along existing or pressure-dependent discontinuities. The model handles ... -

Gas injection laboratory experiments on Opalinus clay.
(2009)
Comunicació de congrés
Accés obertUnderstanding gas transport processes is one of the key issues in the assessment of radioactive waste repository performance and is the focus of this research. To this aim, this research programme was started with ... -
Gas migration in sand/bentonite mixtures through preferential paths
(2011)
Text en actes de congrés
Accés restringit per política de l'editorialSand/bentonite mixtures are considered as buffer material in low and medium radioactive waste disposal schemes. While the bentonite provides low permeability and swelling capacity, the sand is intended to improve mechanical ... -
Gypsum crystal growth in tunnels
(CRC Press. Taylor & Francies Group, 2011)
Comunicació de congrés
Accés restringit per política de l'editorialPrecipitation of gypsum crystals explains the severe swelling occurred in some tunnels crossing sulphate formations. The presence of groundwater and discontinuities, and the proportions of anhydrite and gypsum within the ... -
Heave of a building induced by swelling of an anhydritic Triassic claystone
(2018-09)
Article
Accés obertThis paper describes the conditions leading to a sustained, low-rate, heave phenomenon affecting a building founded on hard Keuper anhydritic rock. The building was located in an abandoned gypsum quarry. Monitoring data ... -
Heave of a building on Keuper anhydritic formation
(International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialThe development of fissures in a building placed at the site of an ancient quarry excavated in a Keuper formation motivated a detailed in-situ investigation of the foundation material. Severe fissures and cracks were present ... -
Heave of a railway bridge induced by gypsum crystal growth: field observations
(2013-07)
Article
Accés restringit per política de l'editorialThe central pillars of a bridge belonging to a recently built high-speed railway line experienced an unexpected and continuous heave after the end of construction. Pillars were founded on 3 × 3 pile groups capped by a rigid ... -
Heave of a railway bridge: modelling gypsum crystal growth
(2013-01)
Article
Accés restringit per política de l'editorialThe heave of the central pillars of a railway bridge, founded on large-diameter bored piles, is a consequence of gypsum crystal growth in an anhydritic claystone stratum underlying the tip of the piles. The heave mechanism ... -

Highly expansive granular mixtures
(CRC Press, 2014)
Text en actes de congrés
Accés restringit per política de l'editorialThe 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 ... -
Hinchamiento en túneles por crecimiento de cristales y su modelación
(Universitat Politécnica de Catalunya. Escola Tècnica Superior d'Enginyers de Camins Canals i Ports de Barcelona, 2011-11-15)
Comunicació de congrés
Accés obertLa intensidad del comportamiento expansivo observado en excavaciones de túneles en arcillas sulfatadas es mayor que en otras rocas y suelos expansivos libres de sulfatos. En la mayoría de casos la funcionalidad y la ... -
HMC analysis of a tunnel in swelling rock
(AEDIFICATIO PUBLISHERS, 2009)
Text en actes de congrés
Accés restringit per política de l'editorialThe phenomenon of swelling in tunnels excavated through sulphate-bearing rock is quite frequent in some geological formations. The paper describes the case of the Lilla tunnel excavated in anhydritic-gypsiferous of Eocene ... -
