    • Effect of soil saturation changes on pressure on tunnel linings 

      de Santos, C.; Ledesma Villalba, Alberto; Lloret Morancho, Antonio (IOS Press, 2009)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      It is well known that changes in soil degree of saturation have an important influence on mechanical soil properties. Decreasing suction in soil leads to an increase of specific weight and to a decrease of stiffness and ...

    • Longitudinal time-dependent response of segmental tunnel linings 

      Arnau Delgado, Oriol; Molins i Borrell, Climent; Blom, C.B.M.; Walraven, Joost C. (2012-03)
      Article
      Accés obert
      The longitudinal forces introduced by tunnel boring machines (TBMs) to the segmental tunnel linings influence their structural response. The analyses of the linings construction process and the ground-structure interaction ...

    • Propuesta de método de optimización de refuerzo de segmentos de túneles fabricados con hormigón reforzado con fibras 

      Fuente Antequera, Albert de la; Galobardes Reyes, Isaac; Domingues de Figueiredo, Antonio; Peixoto, Marco Aurelio (2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The construction of underground lines has a big importance in overpopulated cities such as São Paulo. In that sense, the tunnel boring machine (TBM) method for tunnel construction is a method that allows a high speed of ...

    • Safety format for the flexural design of tunnel fibre reinforced concrete precast segmental linings 

      Cugat Martí, Víctor; Pialarissi Cavalaro, Sergio Henrique; Bairán García, Jesús Miguel; Fuente Antequera, Albert de la (Elsevier, 2020-09)
      Article
      Accés obert
      Fibre reinforced concrete (FRC) is increasingly used in tunnel segmental linings constructed with tunnel boring machines. Several codes include the FRC as a structural material and specific guidelines cover the design of ...

    • Strain-monitoring of a concrete tunnel lining with distributed optical fiber sensors 

      Gómez i Esteve, Judit; Casas Rius, Joan Ramon; Villalba Herrero, Sergi (International Society for Structural Health Monitoring of Intelligent Infrastructure (ISHMII), 2021)
      Text en actes de congrés
      Accés obert
      Despite their advantageous performance and reliability, distributed optical fiber sensors (DOFS) still constitute a recent technology and their reliability and accuracy when applied to real world structures is still under ...

    • Theoretical and numerical analysis of the three-dimensional response of segmental tunnel linings subjected to localized loads 

      Arnau Delgado, Oriol; Molins i Borrell, Climent (2015-06)
      Article
      Accés obert
      Segmental tunnel linings present a significant 3D response when they are subjected to localized loads or to other scenarios that produce different deformations of adjacent rings. The present paper analyzes the interaction ...

    • Three dimensional structural response of segmental tunnel linings 

      Arnau Delgado, Oriol; Molins i Borrell, Climent (2012-11)
      Article
      Accés obert
      The particular configuration of segmental tunnel linings produces that its structural response in front of usual design loads could present a significant three dimensionality due to the structural interaction between ...
