El grup realitza recerca en mecànica de sòls i de les roques i en l'àmbit de la geomecànica en general. També és actiu en un ampli espectre de matèries d'enginyeria geològica i geotècnica, com ara l'estabilitat de talussos, els fonaments, les excavacions, els túnels, l'avaluació de riscos geològics i l'emmagatzematge de residus. La seva activitat en la mecànica de sòls no saturats i l'aplicació de mètodes numèrics avançats és àmpliament reconeguda.

The group carries out research in soil and rock mechanics and in the field of geomechanics in general. It is also active in a wide range of geological and geotechnical engineering fields, such as slope stability, foundations, excavations, tunnels, the evaluation of geological risks, and waste disposal. The group?s activity in unsaturated soil mechanics and in the application of advanced numerical methods is widely recognised.

    This paper reports the results of 3D numerical modelling of a 6-m-high mechanically stabilised earth (MSE) wall constructed with concrete panels and steel or polymeric strip reinforcement. These systems pose numerical ...
  • Study of grain-scale effects in bulk handling using discrete element simulations 

    Torres Serra, Joel; Rodríguez Ferran, Antonio; Romero Morales, Enrique Edgar (2021-04)
    Article
    Restricted access - publisher's policy
    Industrial granular flow issues are affected by the particle properties and environmental conditions of the materials. To understand the impact of grain-scale effects on flowability, experimental testing should be complemented ...
  • Linking shape and rotation of grains during triaxial compression of sand 

    Rorato, Riccardo; Arroyo Alvarez de Toledo, Marcos; Andò, Edward; Gens Solé, Antonio; Viggiani, Gioacchino (2020-11)
    Article
    Restricted access - publisher's policy
    Particle shape has a strong effect on the mechanical response of coarse soils. This has been usually observed examining specimen-scale or engineering-scale responses, which are the sum of many microscale interactions. In ...

    Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos (2015-03)
    Article
    Open Access
    The authors deserve praise for gathering together many different strands of evidence that clarify the mechanics of pile penetration in sand. In their review of numerical approaches to the problem, they correctly indicate, ...
  • Image-based measurements of degree of saturation 

    Parera Morales, Ferran; Pinyol Puigmartí, Núria Mercè; Alonso Pérez de Agreda, Eduardo (E3S Web of Conferences, 2020)
    Conference report
    Open Access
    A method based on SWIR images is proposed for measuring the degree of saturation in soils. This method is especially suitable for use in experiments conducted in the facilities of a common geotechnical laboratory. The ...
  • Probabilistic mapping of earthquake-induced submarine landslide susceptibility in the South-West Iberian margin 

    Collico, Stefano; Arroyo Alvarez de Toledo, Marcos; Urgelés Esclasans, Roger; Gràcia Mont, Eulàlia; Devincenzi, M.J.; Pérez García, Norma (2020-11)
    Article
    Open Access
    The SW Iberian continental margin is well recognized as a tectonically active area, where major canyons and mass wasting events are both present. Earthquake triggered submarine landslides may cause tsunami and result in ...
  • Modelling gas flow in clay materials incorporating material heterogeneity and embedded fractures 

    Puig Damians, Ivan; Olivella Pastallé, Sebastià; Gens Solé, Antonio (Elsevier, 2020-12)
    Article

    A series of gas injection tests on compacted bentonite were carried out at the British Geological Survey. Tests measurements included pressure and rate of gas inflow, gas outflow volume as well as stresses and pore pressure ...
  • Hybrid multi-scale model for partially saturated media based on a pore network approach and lattice Boltzmann method 

    Puig Montellà, Eduard; Yuan, Chao; Chareyre, Bruno; Gens Solé, Antonio (Elsevier, 2020-10)
    Article
    Restricted access - publisher's policy
    A model combining the efficiency of the pore-network (PN) models and the accuracy of the lattice Boltzmann Method (LBM) is proposed. We introduce a multi-scale approach based on a decomposition of the granular assembly ...
  • Landslides in reservoirs and dam operation 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (CRC Press, 2011)
    Part of book or chapter of book
    Restricted access - publisher's policy
    Risk of landslide ocurrence in reservoirs is enhanced by the submergence of the slope toe and by rapid drawdown conditions. Instabilities may endanger the dam itself. They may also lead to strong wave motion in the reservoir ...

    Article
    Restricted access - publisher's policy
    Feeder selection impacts the performance of bagging machinery throughout its life cycle, and yet it is usually based on qualitative assessments of flowability. We propose a data analysis methodology aimed at verifying the ...
