  • A fractal fragmentation model for rockfalls 

    Ruiz Carulla, Roger; Corominas Dulcet, Jordi; Mavrouli, Olga Christina (2017-06)
    Article
    Accés restringit per política de l'editorial
    The impact-induced rock mass fragmentation in a rockfall is analyzed by comparing the in situ block size distribution (IBSD) of the rock mass detached from the cliff face and the resultant rockfall block size distribution ...
  • A methodology to obtain the block size distribution of a large rockfall deposit 

    Ruiz Carulla, Roger; Corominas Dulcet, Jordi; Mavrouli, Olga Christina (2014)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    The block size distribution produced in a rockfall event is necessary for the study of the trajectories, run-out, the impact energies and for the quantitative assessment of the rockfall hazard. For large rockfall deposits, ...

  • Caiguda de blocs als penya-segats del Llobregat al seu pas per Manresa 

    Rabaneda Espinalt, Anna (Universitat Politècnica de Catalunya, 2010-01)
    Projecte/Treball Final de Carrera
    Accés obert
    En aquest projecte es caracteritza la caiguda d’un bloc de grans dimensions de massís rocós d’un penya-segat situat sobre el riu Llobregat al seu pas per Viladordis, a l’est de Manresa, i s’estudien els possibles riscos ...
  • Calculation of the rockwall recession rate of a limestone cliff, affected by rockfalls, using cosmogenic chlorine-36: case study of the Montsec range (Eastern Pyrenees, Spain) 

    Domènech Surinyach, Guillem; Corominas Dulcet, Jordi; Mavrouli, Olga Christina (2018-04)
    Article
    Accés restringit per política de l'editorial
    Cliff erosion may be a major problem in settled areas affecting populations and producing economic and ecological losses. In this paper we present a procedure to calculate the long-term retreat rate of a cliff affected by ...
  • Magnitude and frequency relations: are there geological constraints to the rockfall size? 

    Corominas Dulcet, Jordi; Mavrouli, Olga Christina; Ruiz Carulla, Roger (2018-05)
    Article
    Accés restringit per política de l'editorial
    There exists a transition between rockfalls, large rock mass failures, and rock avalanches. The magnitude and frequency relations (M/F) of the slope failure are increasingly used to assess the hazard level. The management ...
  • Multi-technique approach to rockfall monitoring in the Montserrat massif (Catalonia, NE Spain) 

    Janeras, Marc; Jara Salvador, José Antonio; Royan, Manuel J.; Vilaplana, Joan Manuel; Aguasca Solé, Alberto; Fabregas Canovas, Francisco Javier; Gili Ripoll, José Antonio; Buxó, Pere (2017-03-09)
    Article
    Accés restringit per política de l'editorial
    Montserrat Mountain is located near Barcelona in Catalonia, in the northeast of Spain, and its massif is formed by conglomerate interleaved by siltstone/sandstone with steep slopes very prone to rockfalls. The increasing ...
  • Quantitative rockfall risk assessment in the roadways of Gipuzkoa 

    Corominas Dulcet, Jordi; Mavrouli, Olga Christina (Springer, 2014)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Although many works on the quantification of the rockfall hazard and exposure of vehicles in roadways exist, few practical examples that include detailed consequences analysis have been presented so far. We respectively ...
  • 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)
    Text en actes de congrés
    Accés obert
    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 ...
  • Rockfall occurrence and fragmentation 

    Corominas Dulcet, Jordi; Mavrouli, Olga; Ruiz Carulla, Roger (Springer, 2017)
    Text en actes de congrés
    Accés obert
    Rockfalls are very rapid and damaging slope instability processes that affect mountainous regions, coastal cliffs and slope cuts. This contribution focuses on fragmental rockfalls in which the moving particles, particularly ...

  • 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
    Accés obert
    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 ...
  • Simplified approach for obtaining the block volume distribution of fragmental rockfalls

    Text en actes de congrés
    Accés restringit per política de l'editorial
    Rockfalls are frequent instability processes in road cuts, open pit mines and quarries, steep slopes and cliffs. The attitude and persistency of joints within the rock mass define the size of kinematically unstable rock ...
