Text en actes de congrés
Accés obertLa salinización de suelos es un problema global. Generalmente, la salinización es causada por el transporte de sales hacia la superficie por capilaridad y, a pesar de su importancia global, los mecanismos que la controlan ... -
Short-term thermo-mechanical numerical modelling of reinforced soil walls with polyester strap reinforcements
Moncada Ramírez, Aníbal Andrés; Olivella Pastallé, Sebastià; Puig Damians, Ivan; Bathurst, Richard John (CRC Press, 2023)
Comunicació de congrés
Accés obertPolyester (PET) materials have become more common as reinforcement solution in reinforced soil walls (RSW). It has been shown that strength and stiffness of geosynthetics products, including PET, is load-, time-, and ... -
Simplified approach to analyse global stability of reinforced soil walls
Cañas Pineda, Abercio; Moncada Ramírez, Aníbal Andrés; Olivella Pastallé, Sebastià; Puig Damians, Ivan; Bathurst, Richard John (CRC Press, 2023)
Comunicació de congrés
Accés obertReinforced soil walls (RSW) are a proven alternative to conventional earth retaining structures due to their rapid construction, smaller environmental impact, lower cost, as well as more sustainable social/functional ... -
Some investigations about the tensile strength and the desiccation process of unsaturated clay
Trabelsi, H; Jamei, M.; Guiras, H.; Hatem, H; Romero Morales, Enrique Edgar; Olivella Pastallé, Sebastià (2010-06-10)
Article
Accés obertThe current paper presents an investigation on the tensile strength of unsaturated clay, and a discussion about the significant differences between the behaviours of compacted soils and those of the completely remoulded ... -
Strength reduction analysis in polymeric reinforced soil walls
Moncada Ramírez, Aníbal Andrés; Puig Damians, Ivan; Olivella Pastallé, Sebastià; Bathurst, Richard John (2023)
Comunicació de congrés
Accés restringit per política de l'editorialThe latest revision of EN-1997 allows for the use of numerical tools to design geotechnical structures, provided limit state conditions are thoroughly evaluated were analysis of the construction and post-construction stages ... -
Swelling in clayey soils induced by the presence of salt crystals
Mokni, Nadia; Olivella Pastallé, Sebastià; Alonso Pérez de Agreda, Eduardo (2009-01-20)
Article
Accés restringit per política de l'editorialSeveral coupled flow formulations to model the osmotic processes in clays have been proposed in the literature. These theories were mostly used to model aspects such as osmotically induced consolidation, salt water intrusion ... -
