      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 ...

      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. ...

      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 ...
    • Characterizing a filtered stabilized metallurgical residue with PMT 

      Arroyo Alvarez de Toledo, Marcos; Vargas, Carlos O.; Martínez, Estrella; Salgado, David E. (University of British Columbia (UBC), 2022)
      Text en actes de congrés
      Accés obert
      This paper illustrates how pressuremeter testing may add value to geotechnical characterization of tailing storage facilities (TSF). This is done with reference to results obtained in a campaign on jarosa, a lime-stabilized ...
    • 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 ...
    • El comportamiento de las presas de Baserca y Llauset en los nuevos escenarios energéticos 

      Suárez Arroyo, Benjamín; Miquel Canet, Juan; González Lopez, Jose Manuel; Barbu, Lucia Gratiela; Buil, J.M.; Rio, J.F.; Batlle, M.T. (Sociedad Española de Métodos Numéricos en Ingeniería (SEMNI), 2013)
      Text en actes de congrés
      Accés obert
      Las crecientes demandas energéticas están promoviendo nuevas estrategias comerciales en la explotación de las infraestructuras hidráulicas que se materializan aumentando el protagonismo de los saltos reversibles en la ...
    • 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 ...
