A review on thermo-mechanical modelling of arch dams during construction and operation: effect of the reference temperature on the stress field
Salazar González, Fernando; Vicente González, David Jesús; Irazábal González, Joaquín; Pouplana Sarda, Ignasi de; San Mauro Saiz, Javier (2020-11)
Article
Accés restringit per política de l'editorialDouble-curvature dams are unique structures for several reasons. Their behaviour changes significantly after joint grouting, when they turn from a set of independent cantilevers into a monolithic structure with arch effect. ... -
Análisis experimental y numérico del oleaje producido por la inestabilidad de laderas de embalses
Alves, Ricardo; Morán, Rafael; Toledo Municio, Miguel Ángel; Irazábal González, Joaquín; Salazar González, Fernando; Larese De Tetto, Antonia (2015)
Text en actes de congrés
Accés obertEl fenómeno del oleaje causado por deslizamientos de laderas de embalse un escenario formado por dos procesos, uno de tipo geomecánico y otro, hidrodinámico. El primero está relacionado con el origen de la inestabilidad ... -
Applications of numerical methods in design and evaluation of overtopping protection systems
Salazar González, Fernando; San Mauro Saiz, Javier; Larese De Tetto, Antonia; Irazábal González, Joaquín; Morán Moya, Rafael; Oñate Ibáñez de Navarra, Eugenio; Toledo Municio, Miguel Ángel (Colorado State University, 2016)
Comunicació de congrés
Accés restringit per política de l'editorialThe development of overtopping protection systems often requires detailed analyses of complex physical phenomena. This hinders the comprehensive knowledge of their behavior, and therefore the development of suitable design ... -
Design and validation of rockfall protection systems by numerical modeling with discrete elements
Latorre, Salvador; Celigueta Jordana, Miguel Ángel; Irazábal González, Joaquín; Salazar González, Fernando; Oñate Ibáñez de Navarra, Eugenio (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
Text en actes de congrés
Accés obertRockfall protection systems are installed in order to preserve civil infrastructures against landslides and falling rocks. For the evaluation of these systems,one of the main problems is the difficulty to develop laboratory ... -
Effect of the integration scheme on the rotation of non-spherical particles with the discrete element method
Irazábal González, Joaquín; Salazar González, Fernando; Santasusana Isach, Miquel; Oñate Ibáñez de Navarra, Eugenio (Springer, 2019-10)
Article
Accés obertThe discrete element method (DEM) is an emerging tool for the calculation of the behaviour of bulk materials. One of the key features of this method is the explicit integration of the motion equations. Explicit methods are ... -
Hydraulic and stability analysis of the supporting layer of wedge-shaped blocks
San Mauro Saiz, Javier; Larese De Tetto, Antonia; Salazar González, Fernando; Irazábal González, Joaquín; Morán Moya, Rafael; Toledo Municio, Miguel Ángel (Colorado State University, 2016)
Comunicació de congrés
Accés restringit per política de l'editorialWedge shaped blocks (WSB) are attracting increasing attention as protection against overtopping for earth and rock-fill dams. However, there are limited examples of application and some aspects of the technology merit ... -
Numerical analysis of railway ballast behaviour using the Discrete Element Method.
Irazábal González, Joaquín (Universitat Politècnica de Catalunya, 2017-10-06)
Tesi
Accés obertThe development of high-speed train lines has increased significantly during the last twenty-five years, leading to more demanding loads in railway infrastructures. Most of these infrastructures were constructed using ... -
Numerical modeling of railway ballast using the discrete element method
Irazábal González, Joaquín (Universitat Politècnica de Catalunya, 2015-06)
Projecte Final de Màster Oficial
Accés obert -
Numerical modelling of landslide-generated waves with the particle finite element method (PFEM) and a non-Newtonian flow model
Salazar González, Fernando; Irazábal González, Joaquín; Larese De Tetto, Antonia; Oñate Ibáñez de Navarra, Eugenio (2015)
Article
Accés obertLandslide-generated impulse waves may have catastrophic consequences. The physical phenomenon is difficult to model because of the uncertainties in the kinematics of the mobilised material and to the intrinsic complexity ... -
SOLDIER: SOLution for Dam behavior Interpretation and safety Evaluation with boosted Regression trees
Salazar González, Fernando; Irazábal González, Joaquín; Conde Vázquez, André (2024-02)
Article
Accés obertDecision making in dam safety is fundamentally based on the comparison between the predictions of a behavior model and the records of the monitoring system. Traditionally, simple linear regression models have been used. ... -
The Double Hierarchy Method: a parallel 3D contact method for the interaction of spherical particles with rigid FE boundaries using the DEM
Santasusana, Miquel; Irazábal González, Joaquín; Oñate Ibáñez de Navarra, Eugenio; Carbonell Puigbó, Josep Maria (Springer, 2016-07)
Article
Accés obertIn this work, we present a new methodology for the treatment of the contact interaction between rigid boundaries and spherical discrete elements (DE). Rigid body parts are present in most of large-scale simulations. The ...
