    • Analysis of swelling in tunnels excavated in sulphate claystones 

      Berdugo de Moya, Iván Rafael; Guimarães, Leonardo do N; Alonso Pérez de Agreda, Eduardo; Gens Solé, Antonio; Romero Morales, Enrique Edgar (2009)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The paper summarizes the main phenomenological aspects of swelling in tunnels excavated in sulphate claystones and formulates a series of theoretical consideration for their coupled hydro-mechanical-chemical analysis. The ...

    • Designing tunnel lining in anhydritic claystones: intensity and distribution of swelling forces 

      Alonso Pérez de Agreda, Eduardo; Ramon Tarragona, Anna; Verda, Laura (Springer Nature, 2023-02)
      Article
      Accés obert
      The measured swelling pressures against tunnel linings range between a fraction of one MPa and 6–7 MPa. A strong spatial heterogeneity is often observed. The paper integrates these considerations into a procedure to design ...

    • Hydro-chemo-mechanical modelling of tunnels in sulfated rocks 

      Ramon Tarragona, Anna; Alonso Pérez de Agreda, Eduardo; Olivella Pastallé, Sebastià (Thomas Telford, 2017-11)
      Article
      Accés obert
      A modelling procedure to address the tunnel–anhydritic rock interaction is described in this paper. The model incorporates the basic physico-chemical phenomena involved in rock swelling, often observed during excavation ...

    • Levantamiento de un edificio cimentado sobre roca anhidrítica del Keuper 

      Ramon Tarragona, Anna; Alonso Pérez de Agreda, Eduardo (Sociedad Española de Mecánica del Suelo e Ingeniería Geotécnica, 2016)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      La aparición y aumento de agrietamientos en un edificio situado en el solar de una antigua cantera excavada en el Keuper motivó un reconocimiento detallado del terreno de cimentación. Las plantas sótano, semisótano y baja ...
