  • A repetitive control scheme for distributed solar collector field 

    Berdugo de Moya, Iván Rafael; Costa Castelló, Ramon; Berenguel, M; Yebra, José Luis A. (2010-05)
    Article

    The control of the output fluid temperature in a distributed solar collector field implies accounting for the excitement of its intrinsic resonance modes. Resonance mode frequencies are related to the residence time of the ...
  • A review of expansive phenomena in Wagenburg North Tunnel 

    Berdugo de Moya, Iván Rafael; Alonso Pérez de Agreda, Eduardo; Romero Morales, Enrique Edgar; Gens Solé, Antonio; Albis, María (2009-12-31)
    Article
    Open Access
    The paper deals on tunnelling and swelling in anhydritic-gypsiferous claystones. The geology of the Gipskeuper in Baden-Württemberg (Germany) and the phenomenology of expansions in Wagenburg North tunnel are described. ...
  • 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)
    Conference report
    Restricted access - publisher's policy
    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 ...
  • HMC analysis of a tunnel in swelling rock 

    Berdugo de Moya, Iván Rafael; Guimarães, Leonardo do N; Gens Solé, Antonio; Alonso Pérez de Agreda, Eduardo (AEDIFICATIO PUBLISHERS, 2009)
    Conference report
    Restricted access - publisher's policy
    The phenomenon of swelling in tunnels excavated through sulphate-bearing rock is quite frequent in some geological formations. The paper describes the case of the Lilla tunnel excavated in anhydritic-gypsiferous of Eocene ...
  • Laboratory experiments on swelling due to crystal growth in sulphate argillaceous rocks 

    Deu, Amadeu; Romero Morales, Enrique Edgar; Berdugo de Moya, Iván Rafael (CRC Press, 2013)
    Conference report
    Restricted access - publisher's policy
    Crystal growth is a frequent cause of expansive deformations in natural soils, compacted soils, rocks and concrete. The sulphate crystallization in discontinuities and cracks due to evaporation of highly mineralized solutions ...
  • Tunnelling and swelling in triassic sulphate-bearing rocks: part II: case studies from Jura Mountains 

    Berdugo de Moya, Iván Rafael; Alonso Pérez de Agreda, Eduardo; Romero Morales, Enrique Edgar; Gens Solé, Antonio (2009-06)
    Article
    Open Access
    Part II of this series of paper deals with the phenomenology of swelling in tunnels from Jura Mountains (Switzerland) excavated through the Gipskeuper and the Anhydritgruppe. The main features of expansions observed in the ...
  • Tunnelling and swelling in triassic sulphate–bearing rocks: part I: case studies from Baden–Württemberg 

    Berdugo de Moya, Iván Rafael; Alonso Pérez de Agreda, Eduardo; Romero Morales, Enrique Edgar; Gens Solé, Antonio (2009-06)
    Article
    Open Access
    Cases of swelling in tunnels excavated through Triassic sulphate-bearing rocks from the Gipskeuper and the Anhydritgruppe are presented and discussed in this series of papers in order to gain a better understanding of the ...
  • Tunnelling in sulphate claystones 

    Alonso Pérez de Agreda, Eduardo; Berdugo de Moya, Iván Rafael; Tarragó, Dani; Ramon Tarragona, Anna (IOS Press, 2007)
    Conference report
    Restricted access - publisher's policy
    The paper reviews first the performance of some tunnels built in gypsiferous-anhydritic rocks, especially in Central Europe. Then, a description of the main gypsum-laden lithological rock units in Spain is made as an ...
