    A high-speed railway viaduct experienced a sustained heave at high rates after its construction. The pillars of the bridge are founded on an Eocene hard anhydritic-gypsiferous claystone by means of massive foundations. ...
  • Deformation analysis of landslides: progressive failure, rate effects and thermal interactions 

    Alonso Pérez de Agreda, Eduardo (CRC Press, 2012)
    Conference report
    Restricted access - publisher's policy
    Evaluating landslide risk and its consequences is hardly achieved by “safety factor” concepts, which essentially rely on static equilibrium concepts and forces. Rather, expected displacements, velocities and accelerations ...
  • Degradation effects at microstructural scale and their consequences on macroscopic behaviour of a slightly weathered siltstone. 

    Pineda, Jubert Edgar; Romero Morales, Enrique Edgar; Gómez, Susana; Alonso Pérez de Agreda, Eduardo (CRC Press/Balkema, 2010)
    Conference lecture

    A systematic experimental programme was performed on a slightly weathered siltstone of Weald facies (Cretaceous period) to study the degradability of the material due to hydraulic and mechanical processes. The paper ...
  • Design of micropiles for tunnel face reinforcement: undrained upper bound solution 

    Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (2012-01)
    Article
    Restricted access - publisher's policy
    The stability of tunnel faces supported by an umbrella of subhorizontal micropiles is analyzed by means of the upper bound theorem of plasticity. The micropiles are considered beams subjected to the kinematic motion imposed ...
  • Discussion on “Large landslides associated with a diapiric fold in Canelles reservoir (Spanish Pyrenees): Detailed geological–geomorphological mapping, trenching and electrical resistivity imaging” by Gutiérrez et al. (2015)
