    • A review of Beliche Dam 

      Alonso Pérez de Agreda, Eduardo; Olivella Pastallé, Sebastià; Pinyol Puigmartí, Núria Mercè (Institution of Civil Engineers (http://www.ice.org.uk/), 2005)
      Article
      Accés obert
      Beliche 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 ...
    • Application of a critical state model to the Merriespruit tailings dam failure 

      Mánica Malcom, Miguel Ánge; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; Monforte Vila, Lluís (2022-04)
      Article
      Accés obert
      The use of stress–deformation analyses to evaluate the characteristics of possible static liquefaction events is rapidly becoming the norm for tailings dams exposed to such risk. Ideally, those analyses should be based on ...
    • Aznalcóllar dam failure. Part 1: Field observations and material properties 

      Alonso Pérez de Agreda, Eduardo; Gens Solé, Antonio (Institution of Civil Engineers (http://www.ice.org.uk/), 2006)
      Article
      Accés obert
      The paper describes the failure of Aznalcóllar dam, in southern Spain, in April 1998. The rockfill dam slid forward and released a flow of acid-saturated tailings. The geology and geomorphology of the site are described. ...
    • Aznalcóllar dam failure. Part 2: Stability conditions and failure 

      Gens Solé, Antonio; Alonso Pérez de Agreda, Eduardo (Institution of Civil Engineers (http://www.ice.org.uk/), 2006)
      Article
      Accés obert
      An analysis of the conditions that led to the failure of the Aznalcóllar dam is made in the paper. Pore water pressures prevailing in the foundation clay at the time of the failure have been established on the basis of ...
    • Aznalcóllar dam failure. Part 3: Dynamics of the motion 

      Gens Solé, Antonio; Alonso Pérez de Agreda, Eduardo (Institution of Civil Engineers (http://www.ice.org.uk/), 2006)
      Article
      Accés obert
      The motion of the Aznalcóllar dam slide, after the initiation of the failure, is examined in the paper. The moving mass remained essentially rigid, and Newton’s second law provides the basic equation to determine the ...
    • Effects of tailings viscosity on liquefaction triggering analyses 

      Mánica Malcom, Miguel Ánge; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (University of Alberta, 2021)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Recent analyses have suggested that creep or rate effects may be present in some tailings and can play a role in triggering liquefaction failure. However, the role of creep in liquefaction triggering analysis of tailing ...
    • Exploring viscous effects on numerical simulations of static liquefaction triggering 

      Pinedo Vilcahuamán, Paul José; Besenzon, Davide; Mánica Malcom, Miguel Ángel; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (Gecamin, 2022)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Failures due to static liquefaction have been too frequent in tailings dams. Stress-deformation numerical analyses based on critical state theory are able to reproduce those failures and may be used to gain insight into ...
    • Influence of the particle size distribution on the Critical State Properties of Mine Tailings 

      Vergaray, Luis; Macedo, Jorge; Cody, Arnold; Arroyo Alvarez de Toledo, Marcos (University of British Columbia (UBC), 2022)
      Text en actes de congrés
      Accés obert
      Arguably, critical state soil mechanics (CSSM) is now the preeminent methodology for understanding static liquefaction of mine tailings, having been used in the mining industry by the expert panels retained to investigate ...
    • La rotura de la presa de relaves de Brumadinho: la montaña de cristal 

      Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2022)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      En Enero de 2019 en Brumadinho (Brasil) una presa de relaves mineros de gran tamaño colapsó en su totalidad de forma brusca, causando la muerte a 270 personas y una gran conmoción en la minería mundial. La rotura fue ...
    • Tailings desiccation process studied in environmental chamber experiment 

      Garino Libardi, Lucas Martín; Oldecop, Luciano Agustín; Romero Morales, Enrique Edgar; Rodríguez Pacheco, Roberto Lorenzo (2022-04)
      Article
      Accés obert
      Case studies and numerical simulations show that the long-term stability of tailings dams largely depends on the evolution of their water content. Therefore, desiccation is one of the critical processes influencing the ...
