    • Aceleración de deslizamientos por efectos térmicos: modelación mediante el método del punto material 

      Alvarado Bueno, Mauricio; Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (2017)
      Text en actes de congrés
      Accés obert
      La ocurrencia de deslizamientos rápidos se ha ligado a la pérdida de resistencia efectiva a lo largo de la superficie de rotura debido a excesos de presión de agua inducidos por el calor generado durante el propio movimiento. ...

    • Dynamics of slow and fast landslides 

      Pinyol Puigmartí, Núria Mercè; Alvarado Bueno, Mauricio; García Núñez, Luis Miguel (2020)
      Text en actes de congrés
      Accés obert
      The paper discusses some factors that control the shearing soil behaviour and the dynamics of landslides: strain-, strain rate-, and temperature effects. The strain rate effect on residual strength is discussed through ...

    • Efectos del cambio de la velocidad de deformación sobre la resistencia del suelo: aplicación del método del punto material 

      Alvarado Bueno, Mauricio (Universitat Politècnica de Catalunya, 2013-12-13)
      Projecte Final de Màster Oficial
      Accés obert
      La velocidad de deformación afecta las propiedades mecánica de un suelo tanto en su estado inalterado (propiedades pico) como en estado residual. Este efecto conocido como “Rate effects”, ha sido estudiado en laboratorio ...

    • Effect of shear band thickness on the termo-hydromechanical coupled analysis of landslides 

      Pinyol Puigmartí, Núria Mercè; Alvarado Bueno, Mauricio; Alonso Pérez de Agreda, Eduardo (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
      Text en actes de congrés
      Accés obert
      Thermal effects induced by the own motion of an unstable mass have been included in the analysis of the post-failure behavior in early works, most of them with the aim of looking for the causes of the rapid acceleration ...

    • Landslide motion assessment including rate effects and thermal interactions: revisiting the Canelles landslide 

      Alvarado Bueno, Mauricio; Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (2019-09)
      Article
      Accés obert
      The re-activation of a large (40 Mm3) landslide on the valley slopes of a reservoir motivated a research initiative to estimate the risk of a fast-sliding mass moving into the reservoir. A previous simplified analysis had ...

    • Landslide motion assessment including thermal interaction : an MPM approach 

      Alvarado Bueno, Mauricio (Universitat Politècnica de Catalunya, 2018-04-23)
      Tesi
      Accés obert
      Risk associated with landslides of natural or man-made origin depends on the prediction of the post-failure behaviour of the mobilized mass. Numerical models capable of integrating the landslide geometry and its evolution, ...

    • Novel analysis for large strains based on particle image velocimetry 

      Pinyol Puigmartí, Núria Mercè; Alvarado Bueno, Mauricio (2017-07)
      Article
      Accés obert
      Over the last few decades, the particle image velocimetry (PIV) technique has become an interesting tool used to measure displacements in the field of experimental mechanics. This paper presents a procedure to interpret ...

    • Novel procedure to validate MPM results by means of PIV measurements 

      Pinyol Puigmartí, Núria Mercè; Alvarado Bueno, Mauricio; Parera Morales, Ferran; Yerro Colom, Alba (2017-02)
      Article
      Accés obert
      The Particle Image Velocimetry is a powerful non-invasive technique to analyse displacements in experimental tests. Displacement increments elapsed between the capture of two digital images are commonly measured on points ...

    • Nuevo método para la interpretación de imágenes digitales de inestabilidad mediante la técnica PIV. 

      Alvarado Bueno, Mauricio; Ruiz, Álvaro; Pinyol Puigmartí, Núria Mercè (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
      Text en actes de congrés
      Accés obert
      Este artículo presenta una metodología que proporciona los desplazamientos acumulados, velocidad, aceleración y deformación de puntos asociados a partículas reales a partir de las medidas obtenidas mediante la técnica ...

    • Thermal effects in landslide mobility 

      Pinyol Puigmartí, Núria Mercè; Alvarado Bueno, Mauricio; Alonso Pérez de Agreda, Eduardo; Zabala, Francisco (Thomas Telford, 2018-06)
      Article
      Accés restringit per política de l'editorial
      The paper describes a thermo-hydro-mechanical formulation to model thermal-induced effects due to the irreversible work input generated during the soil deformation. The model was implemented into a Material Point calculation ...

    • Thermal interaction in shear bands: the Vajont landslide 

      Alvarado Bueno, Mauricio; Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (CRC Press, 2019)
      Capítol de llibre
      Accés restringit per política de l'editorial
      The localization of strains in landslide shearing surfaces may induce relevant weakening processes due to the thermal pressurization of the pore water filling the pores. The associate reduction in strength can explain the ...

    • Wetting collapse and failure of and slope tested in centrifuge machine 

      Pinyol Puigmartí, Núria Mercè; Ruiz, Álvaro; Alvarado Bueno, Mauricio; Caicedo, Bernardo (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
