  • Heave of a railway bridge induced by gypsum crystal growth: field observations 

    Alonso Pérez de Agreda, Eduardo; Ramon Tarragona, Anna (2013-07)
    Article
    Restricted access - publisher's policy
    The central pillars of a bridge belonging to a recently built high-speed railway line experienced an unexpected and continuous heave after the end of construction. Pillars were founded on 3 × 3 pile groups capped by a rigid ...
  • Heave of a railway bridge: modelling gypsum crystal growth 

    Ramon Tarragona, Anna; Alonso Pérez de Agreda, Eduardo (2013-01)
    Article
    Restricted access - publisher's policy
    The heave of the central pillars of a railway bridge, founded on large-diameter bored piles, is a consequence of gypsum crystal growth in an anhydritic claystone stratum underlying the tip of the piles. The heave mechanism ...
  • Heaven and Hell Tilings 

    Dress, Andreas W. M.; Huson, Daniel H. (Université du Québec à Montréal, 1991)
    Article
