    Minor thesis
    Open Access
    En aquesta tesina es realitza un estudi de moviments superficials mitjançant la tècnica d’interferometria radar (DInSAR) a la zona del poble de Súria. És una àrea on la possibilitat d’observar deformacions del terreny ...
  • Mathematical modelling of slopes 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè; Yerro Colom, Alba (Elsevier, 2014)
    Article
    Open Access
    The paper discusses first the effect of rainfall on the stability of slopes and it focusses on the role of permeability. Existing or induced discontinuities are shown to have a remarkable effect on the slope safety. Also, ...
  • Modelling large deformation problems in unsaturated soils 

    Yerro Colom, Alba; Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (E3S Web of Conferences, 2016)
    Conference report
    Open Access
    Applications of unsaturated soil mechanics often involve large deformations and displacements. This is the case of collapse behaviour of low density soils or the unrestrained swelling of expansive clays. Rain induced ...
  • Modelling progressive failure with MPM 

    Yerro Colom, Alba; Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (CRC Press Taylor & Francis Group, 2014)
    Conference report
    Restricted access - publisher's policy
    In this work, the progressive failure phenomenon is studied using the Material Point Method (MPM). MPM is categorized as a method in between the classical Finite Element Method (FEM) and the truly particle methods. It is ...
  • Modelling the initiation and run-out of rainfall-induced slope instability 

    Yerro Colom, Alba; Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (2016)
    Conference report
    Restricted access - publisher's policy
    Rain induced instabilities are a common geotechnical problem specially in partially saturated soils. A large number of steep, natural or cut slopes remain stable for a long time and then fail during heavy rainstorms or ...
  • MPM modelling of landslides in brittle and unsaturated soils 

    Yerro Colom, Alba (Universitat Politècnica de Catalunya, 2015-11-10)
    Doctoral thesis
    Open Access
    Landslides and slope instabilities represent one of the most important problems in geotechnics causing significant damages around the world every year. Understanding the mechanics of the whole process is of particular ...
  • 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
    Open Access
    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 ...
  • Recent developments of the Material Point Method for the simulation of landslides 

    Alonso Pérez de Agreda, Eduardo; Yerro Colom, Alba; Pinyol Puigmartí, Núria Mercè (2015-09)
    Article
    Open Access
    The paper describes first the theoretical framework of a "single layer" three phase material. The formulation is general and particular cases are dry and fully saturated soils. The formulation and discretization of the ...
  • Run-out of landslides in brittle soils 

    Yerro Colom, Alba; Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (2016-03)
    Article
    Open Access
    One of the factors causing the acceleration of landslides is the loss of strength of the soil involved in the potential unstable mechanism. The travelled distance and the landslide velocity, a key factor in risk analysis, ...
  • Run-out of landslides in brittle soils: an MPM anlysis 

    Yerro Colom, Alba; Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (CRC Press, 2014)
    Conference report
    Restricted access - publisher's policy
    In this paper a slope stability problem due to an increase of the pore pressure is analysed by means of the material point method (MPM). A strain softening model is implemented and the progressive failure is examined in ...
  • Solving hydro-mechanical problems with the material point method 

    Yerro Colom, Alba (IOS Press, 2011)
    Conference report
    Open Access
    This paper presents the ongoing work aimed at developing the material point method (MPM) to solve geomechanical problems. Although MPM is usually classified as a mesh-free method, it might rather be classified as a method ...
  • The Material Point Method: a promising computational tool in Geotechnics
