    RESUMENLa caída de bloques de roca sobre infraestructuras y zonas urbanizadas causa elevados daños y alguna víctima cada año en nuestro país. Los modelos de propagación existentes no tienen en cuenta la fragmentación durante ...
  • Effect of rockfall fragmentation on exposure and subsequent risk analysis 

    Matas Casado, Gerard; Corominas Dulcet, Jordi; Lantada Zarzosa, Maria de Las Nieves (2018)
    Conference report
    Open Access
    Rockfalls are frequent natural processes in mountain regions with the potential to produce damage. The quantitative risk analysis (QRA) is an approach increasingly used to assess risk and evaluate the performance of ...
  • Experimental study on rockfall fragmentation: in situ test design and first results

    Corominas Dulcet, Jordi; Matas Casado, Gerard; Ruiz Carulla, Roger (2019-01)
    Article
    Restricted access - publisher's policy
    Rockfalls are ubiquitous diffuse hazard in mountain regions, cliffs, and cutslopes, with the potential of causing victims and severely damaging buildings and infrastructures. A vast majority of detached rock masses break ...
  • Rockfall fragmentation analysis: Vilanova de Banat case study 

    Matas Casado, Gerard; Lantada Zarzosa, Maria de Las Nieves; Corominas Dulcet, Jordi; Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Prades Valls, Albert (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2017)
    Conference report
    Open Access
    Fragmentation is a critical mechanism for the calculation of the trajectories of the blocks and the impact energies, for the assessment of the potential damage and for the design of protec-tive structures, although few ...
  • RockGIS: a GIS-based model for the analysis of fragmentation in rockfalls 

    Matas Casado, Gerard; Lantada Zarzosa, Maria de Las Nieves; Corominas Dulcet, Jordi; Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Prades Valls, Albert (2017-03-31)
    Article
    Open Access
    A rockfall is a mass instability event frequently observed in road cuts, open pit mines and quarries, steep slopes and cliffs. After its detachment, the rock mass may disaggregate and break due to the impact with the ground ...
  • Seismic energy analysis as generated by impact and fragmentation of single-block experimental rockfalls 

    Salo Salgado, Lluis; Corominas Dulcet, Jordi; Lantada Zarzosa, Maria de Las Nieves; Matas Casado, Gerard; Prades Valls, Albert; Ruiz Carulla, Roger (American Geophysical Union (AGU), 2018-06)
    Article
