    • Anisotropic deformability and strength of slate from NW-Spain 

      Alejano, Leandro R.; González Fernández, María África; Estévez Ventosa, Xian; Song, Fei; Delgado Martin, Jorge José; Muñoz Ibáñez, Andrea; González Molano, N.; Alvarellos Iglesias, José (Elsevier, 2021-12)
      Article
      Open Access
      Slates are metamorphic rocks characterized by the pervasive occurrence of cleavage or foliation producing a highly anisotropic mechanical behavior characterized by fissility. Deformability and strength of these rocks are ...

    • Comportamiento post-rotura de los macizos rocosos: y su aplicación al diseño de excavaciones subterráneas 

      Rodríguez Dono, Alfonso; Alejano, Leandro R. (2012)
      Book
      Restricted access - publisher's policy
      El incremento de las obras mineras y civiles también ha aumentado lógicamente el número de percances ocasionados por éstas, principalmente en lo que concierne a la etapa de construcción, pero también a la de explotación o ...

    • Numerical analysis of anisotropic stiffness and strength for geomaterials 

      Song, Fei; González Fernández, Manuel A.; Rodríguez Dono, Alfonso; Alejano, Leandro R. (Science Press, 2023-02)
      Article
      Open Access
      In numerical modelling, selection of the constitutive model is a critical factor in predicting the actual response of a geomaterial. The use of oversimplified or inadequate models may not be sufficient to reproduce the ...

    • Numerical modelling of tunnel based on a non-contact geological survey method 

      Ferrero, Anna María; Migliazza, Maria Rita; Alejano, Leandro R.; Rodríguez Dono, Alfonso (2011)
      Conference report
      Restricted access - publisher's policy
      The development of new methods for the geostructural survey that do not need direct contact with the rock mass have been developed by several authors and applied to rock slopes. The new idea of this work was to apply a ...

    • Toppling susceptibility of a single rock block resting on a regularly rough base 

      Gui, Jing-Yun; González Fernández, Manuel A.; Estévez Ventosa, Xian; Song, Fei; Alejano, Leandro R. (2023-02)
      Article
      Open Access
      Toppling of individual rock blocks resting on an inclined surface has often been observed in nature. This instability mechanism has typically been analysed for simple block geometries, considering the contact between the ...
