    Article
    Accés restringit per política de l'editorial
    A 100 m high gravity dam (Castrovido dam, Burgos, Spain) is founded on a soft Weald red claystone with inter-bedded sandstone strata. Claystone weathering was identified in vertical and horizontal profiles of water content ...
  • Small scale slope failure benchmark test: modelling and prediction 

    Hoffmann Jauge, Christian; Meler Payán, Nuria; Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (Elsevier, 2014)
    Article
    Accés obert
    A benchmark was designed with the aim of evaluating the capabilities of current modelling techniques and computational codes to reproduce slope failures. Laboratory tests and three instrumented small scale experiments of ...
  • Mathematical modelling of slopes 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè; Yerro Colom, Alba (Elsevier, 2014)
    Article
    Accés obert
    The paper discusses first the effect of rainfall on the stability of slopes and it focusses on the role of permeability. Existing or induced discontinuities are shown to have a remarkable effect on the slope safety. Also, ...
  • Heave of a building induced by swelling of an anhydritic Triassic claystone 

    Ramon Tarragona, Anna; Alonso Pérez de Agreda, Eduardo (2018-09)
    Article
    Accés restringit per política de l'editorial
    This paper describes the conditions leading to a sustained, low-rate, heave phenomenon affecting a building founded on hard Keuper anhydritic rock. The building was located in an abandoned gypsum quarry. Monitoring data ...

    Torres Serra, Joel; Romero Morales, Enrique Edgar; Rodríguez Ferran, Antonio (Multidisciplinary Digital Publishing Institute (MDPI), 2018-07)
    Article
    Accés obert
    A wide range of bulk materials with different physical properties are nowadays handled in the packaging industry using different material conveying techniques. Nevertheless, experimental methodologies to characterise ...
  • Marchetti flat dilatometer tests in a virtual calibration chamber 

    Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos; Amoroso, Sara; Gens Solé, Antonio (2018-09)
    Article
    Accés restringit per política de l'editorial
    Calibration chambers are frequently used to verify, adapt, or both verify and adapt empirical relations between different state variables and in situ test results. Virtual calibration chambers (VCC) built with 3D discrete ...
  • Boundary effects in the desiccation of soil layers with controlled environmental conditions 

    Lakshmikantha, Ramasesha Mookanahallipatna; Prat Catalán, Pere; Ledesma Villalba, Alberto (2018-07)
    Article
    Accés restringit per política de l'editorial
    This article presents the results of an experimental research carried to investigate the mechanics of cracking of soil layers under drying conditions. The tests were conducted under controlled laboratory conditions and in ...
  • Monitoring of a full-scale embankment experiment regarding soil–vegetation–atmosphere interactions 

    Oorthuis Gómez, Raül; Hurlimann Ziegler, Marcel; Fraccica, Alessandro; Lloret Morancho, Antonio; Moya Sánchez, José; Puig i Polo, Càrol; Vaunat, Jean (2018-06)
    Article
    Accés obert
    Slope mass-wasting like shallow slides are mostly triggered by climate effects, such as rainfall, and soil–vegetation–atmosphere (SVA) interactions play a key role. SVA interactions are studied by a full-scale embankment ...
