    Conference report
    Open Access
    The effect of climate change on soil loss processes in mountainous areas represents a current and critical problem. In this work, this issue is addressed through the analysis of the stability of different types of slopes ...
  • Effect of land cover and climate changes on rainfall-induced landslides: regional-scale modelling in the Val d’Aran (Pyrenees, Spain) 

    Hurlimann Ziegler, Marcel; Medina Iglesias, Vicente César de; Lloret Morancho, Antonio; Vaunat, Jean; Puig i Polo, Càrol; Moya Sánchez, José (International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2021)
    Conference report
    Open Access
    The analysis of the impacts of future environmental changes on rainfall-induced landslides is of great importance. Recent studies have shown that these changes will affect the frequency and magnitude of shallow slides and ...
  • Analysis of massive sulphate attack to cement-treated compacted soils 

    Ramon Tarragona, Anna; Alonso Pérez de Agreda, Eduardo (E3S Web of Conferences, 2020)
    Conference report
    Open Access
    The paper describes the heave experienced by two embankments providing access to a bridge located in a high-speed railway line. The compacted soil, a mixture of a low plasticity clay, sand and gravel, had a significant ...
  • Incorporating surface roughness into DEM models of crushable soils 

    Zhang, Ningning; Arroyo Alvarez de Toledo, Marcos; Ciantia, Matteo Oryem; Gens Solé, Antonio (ITASCA Consulting Group, 2020)
    Conference report
    Restricted access - publisher's policy
    One obvious characteristic of granular grains is that their surface is not smooth, especially when observed at smaller scales. Some advanced experiment imaging methods such as optical interferometry, scanning electron ...
  • Microscopic calibration of rolling friction to mimic particle shape effects in DEM 

    Rorato, Riccardo; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio; Andò, Edward (ITASCA Consulting Group, 2020)
    Conference report
    Restricted access - publisher's policy
    Much work has been done to characterize granular shape and to understand its influence on overall soil behavior. Thus, Wadell (Wadell 1932) introduced the concept of “sphericity” that quantifies how a particle differs from ...
  • Insight into decision support systems for sustainable geotechnical engineering 

    Karagianni, Pavlina; Romero Morales, Enrique Edgar; Mariano, Alessandra di; Priegue Mayán, Ángel Diego (EWG-DSS — EURO Working Group on Decision Support Systems, 2019)
    Conference report
    Open Access
    Geotechnical engineering has a significant role in sustainability, due to its early place in the construction process and thus with a higher possibility to limit the impact of the project. Nevertheless, there is a lack of ...
  • 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 ...
  • Laboratory experiments in soil mechanics by means of digital twins and low-cost equipment 

    Ledesma Villalba, Alberto; Prat Catalán, Pere; Lloret Morancho, Antonio; Chacón Flores, Rolando Antonio; Sondon Sansó, Mercedes (International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2020)
    Conference report
    Restricted access - publisher's policy
    The Soil Mechanics Laboratory has been traditionally an important issue in most courses on Soil Mechanics and Geotechnical Engineering. Nowadays, the available technology allows to build low cost systems that brings the ...
  • Calibración con cálculos dinámicos no lineales del método de Newmark para análisis de estabilidad sísmica de laderas 

    Dong, Shan; López Almansa, Francisco; Ledesma Villalba, Alberto (Asociación Chilena de Sismología e Ingeniería Antisísmica, 2019)
    Conference report
    Open Access
    El método de Newmark es un procedimiento simplificado para analizar la estabilidad de laderas sometidas a acciones sísmicas. En esta formulación se considera un bloque infinitamente rígido situado sobre una superficie ...
  • Identificación no lineal de movimientos sísmicos en el lecho rocoso ingenieril a partir de registros tomados en la superficie 

    Rodríguez Sánchez, Julio; López Almansa, Francisco; Ledesma Villalba, Alberto (Asociación Chilena de Sismología e Ingeniería Antisísmica, 2019)
    Conference report
    Open Access
    En ingeniería sísmica, los registros disponibles suelen ser superficiales y, en consecuencia, los movimientos en las capas inferiores deben ser estimados conociendo el perfil estratigráfico del terreno; estos movimientos ...
  • Coupled THM analysis of long-term anisotropic convergence in the full-scale micro tunnel excavated in the Callovo-Oxfordian argillite 

    Tourchi, Saeed; Vaunat, Jean; Gens Solé, Antonio; Vu, M. N.; Bumbieler, F. (International Centre for Numerical Methods in Engineering (CIMNE), 2019)
