    • Seismic energy analysis as generated by impact and fragmentation of single-block experimental rockfalls 

      Salo Salgado, Lluis; Corominas Dulcet, Jordi; Lantada, Nieves; Matas Casado, Gerard; Prades Valls, Albert; Ruiz Carulla, Roger (American Geophysical Union (AGU), 2018-06)
      Article
      Accés obert
      The analysis of seismic signals obtained from near-source triaxial accelerometer recordings of two sets of single-block rockfall experiments is presented. The tests were carried out under controlled conditions in two ...

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

      Corominas Dulcet, Jordi; Mavrouli, Olga Christina; Santana, Dulcis; Moya Sánchez, José (CRC Press. Taylor & Francies Group, 2013)

    • Simulación de desprendimientos rocosos con fragmentación mediante RockGIS 

      Matas Casado, Gerard; Lantada, Nieves; Corominas Dulcet, Jordi (International Centre for Numerical Methods in Engineering (CIMNE), 2022)
      Text en actes de congrés
      Accés obert
      La fragmentación en desprendimientos rocosos es un fenómeno complejo y poco comprendido que afecta a la evaluación del peligro y del riesgo. Sólo algunos modelos de simulación de caídas de rocas lo consideran explícitamente. ...

    • Simulation of full-scale rockfall tests with a fragmentation model 

      Matas Casado, Gerard; Lantada, Nieves; Corominas Dulcet, Jordi; Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Prades Valls, Albert (2020-05)
      Article
      Accés obert
      In this paper, we present the upgraded version of RockGIS, a stochastic program for the numerical simulation of rockfalls and their fragmentation, based on a fractal model. The code has been improved to account for a range ...

    • Simulation of rockfall fragmentation mechanism in a GIS-based tool 

      Matas Casado, Gerard; Lantada, Nieves; Corominas Dulcet, Jordi; Gili Ripoll, José Antonio (CRC Press, 2016)
      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 ...

    • Size distribution for potentially unstable rock masses and in situ rock blocks using LIDAR-generated digital elevation models 

      Mavrouli, Olga Christina; Corominas Dulcet, Jordi; Jaboyedoff, M. (2015-07-01)
      Article
      Accés obert
      In this paper, two analytical procedures which are independent from the existence of empirical data are presented for the calculation of (1) the size distribution of potentially unstable rock masses that expresses the ...

    • Técnicas geomáticas como herramienta en el estudio de desprendimientos rocosos 

      Lantada, Nieves; Núñez Andrés, María Amparo; Corominas Dulcet, Jordi; Prades Valls, Albert; Matas Casado, Gerard; Buill Pozuelo, Felipe; Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Puig i Polo, Càrol; Moya Sánchez, José (Ilustre Colegio Oficial de Ingenieros Técnicos en Topografía de España, 2022)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Los desprendimientos de rocas son fenómenos naturales que se producen de forma muy puntual en el tiempo, y que por lo general afectan a infraestructuras con alto impacto económico y social para la población. Por ello, el ...

    • The physical vulnerability of roads to debris flows: an expert judgement approach 

      Smith, Jessica; Winter, Mike; Fotopoulou, Stavroula; Pitilakis, Kyiriazis; Mavrouli, Olga Christina; Corominas Dulcet, Jordi; Argyroudis, Sotiris (CRC Press. Taylor & Francies Group, 2013)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The physical vulnerability of roads to debris flow is expressed through fragility functions that relate flow volume to damage probabilities. Fragility relationships are essential components of quantitative risk assessments ...

    • The RockRisk project: rockfall risk quantification and prevention 

      Corominas Dulcet, Jordi; Lantada, Nieves; Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Matas Casado, Gerard; Mavrouli, Olga Christina; Núñez Andrés, María Amparo; Moya Sánchez, José; Buill Pozuelo, Felipe; Abellán Fernández, Antonio; Puig i Polo, Càrol; Prades Valls, Albert; Martínez Bofill, Joan; Salo Salgado, Lluis (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2017)
      Text en actes de congrés
      Accés obert
      Realitzat a/amb:   Universiteit Twente / Scott Polar Research Institute
      Rockfalls are frequent instability processes in road cuts, open pit mines and quarries, steep slopes and cliffs. The orientation and persistence of joints within the rock mass define the size of the kinematically unstable ...
