    The paper presents the work carried out to assess and simulate numerically the phenomenology behind the response of large diameter intermediate-level long-lived nuclear waste (ILW-LL) storage galleries and the corresponding ...
  • PFEM analysis of installation effects on axial performance of jacked piles in chalk 

    Ciantia, Matteo Oryem; Lei, Jiangtao; Monforte Vila, Lluís; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
    Conference report
    Open Access
    Chalk is present in a large area of the East and South coast of the UK where renewables are now being installed. In most cases they are founded on displacement piles, whose design uses empirical methods or partial ...
  • Grain roughness effect on the critical state line of crushable sands 

    Lei, Jiangtao; Arroyo Alvarez de Toledo, Marcos; Ciantia, Matteo Oryem; Zhang, Ningning (University of Dundee, 2021)
    Conference report
    Open Access
    A recently proposed DEM model for materials with rough crushable grains (Zhang et al. 2021; Ciantia et al. 2015; Otsubo et al. 2017) is here employed to examine the effect of contact roughness on the critical state line, ...
  • Interferometric SAR deformation timeseries: a quality index 

    Abera Wassie, Yismaw; Mirmazloumi, Seyedmohammad; Monserrat Hernández, Oriol; Crippa, Bruno; Palamá, Riccardo; Barra, Anna; Crosetto, Michele (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2021)
    Conference report
    Open Access
    Estimating unknown absolute phase from a wrapped observation is a challenging and ill-posed problem that possibly leads to misinterpretation of interferometric SAR (InSAR) deformation results. In this study, we introduce ...
  • Numerical modelling of two-phase flow in fractured rock masses using zero-thickness interface elements 

    Barandiarán Villegas, Lucía Belén; Liaudat, Joaquín; López Garello, Carlos María; Carol, Ignacio (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
    Conference report
    Open Access
    In recent years, the authors and co-workers have developed a 3D finite element model for coupled thermo-hydro-mechanical (THM) problems in fractured rock masses. Zero-thickness interface elements are used for taking into ...
  • New results in 3D-mesomechanical coupled analysis of external sulphate attack in concrete 

    Biscaro, Caterina; Martínez Estévez, Ariadna; Pérez Carreras, Adrià; López Garello, Carlos María; Xotta, G.; Carol, Ignacio (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
    Conference report
    Open Access
    External Sulphate Attack (ESA) is one of the main degradation processes affecting concrete structures. It takes place when the concrete is in an environment rich in sulphate ions and with a high humidity index. Once it has ...
  • TLS- and inventory-based Magnitude – Frequency relationship for rockfall in Montserrat and Castellfollit de la Roca 

    Janeras Casanova, Marc; Pedraza Royo, Oriol; Lantada, Nieves; Núñez Andrés, María Amparo; Hantz, Didier; Palau, Joan (Chutes de Blocs Risques Rocheux Ouvrages de Protection, 2021)
    Conference lecture
    Open Access
    Hazard scenarios are defined by a representative event of a certain magnitude, which corresponds to a frequency of occurrence or annual probability. In rockfall, scenario magnitude is identified by the total volume detached. ...
  • Laboratory test to study the effect of comminution in rockfalls 

    Matas Casado, Gerard; Parra, E.; Lantada, Nieves; Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Corominas Dulcet, Jordi; Moya Sánchez, José; Prades Valls, Albert; Buill Pozuelo, Felipe; Núñez Andrés, María Amparo; Puig i Polo, Càrol (2021)

    Fragmentation in rockfalls reduces the size of the blocks and increases the number of fragments. It affects the runout and the impact energies, having implications in the associated hazard and therefore in the subsequent ...
  • Using several monitoring techniques to measure the rock mass deformation in the Montserrat Massif 

    Janeras Casanova, Marc; Jara Salvador, José Antonio; López Pacheco, Ferran; Marturiá Alavedra, Jordi; Royan, Manuel J.; Vilaplana Fernández, Joan Manuel; Aguasca Solé, Alberto; Fabregas Canovas, Francisco Javier; Cabranes, Fabián; Gili Ripoll, José Antonio (Institute of Physics (IOP), 2015)

    Montserrat Mountain is located near Barcelona in Catalonia, at the north-east cornerof Spain, and its massif is formed by conglomerate interleaved by siltstone/sandstone withsteep slopes very prone to rock ...
  • Applying Bayesian updating to CPT data analysis 

    Collico, Stefano; Pérez, N.; Devincenzi, M.J.; Arroyo Alvarez de Toledo, Marcos (CRC Press, 2018)
    Conference lecture
    Open Access
    Evaluation of geotechnical parameters on a project site is a necessary step in geotechnical engineering. However, due to the inherent variability of soil properties and the lack of data, many unavoidable uncertainties arise ...
  • Sample quality examination on silty soils 

    Arroyo Alvarez de Toledo, Marcos; Pineda Jiménez, Jubert Andrés; Sau Valenzuela, Núria; Devincenzi, M.J.; Pérez, N. (Institution of Civil Engineers (ICE), 2015)
    Conference lecture
