(2007)
Text en actes de congrés
Accés obertSe presenta una serie de roturas en las que fue posible comparar los ángulos de fricción derivados mediante análisis retrospectivo con los obtenidos en ensayos de laboratorio utilizando técnicas diferentes. Cuando el ... -
Rapid drawdown and landslides
(CRC Press, 2012)
Text en actes de congrés
Accés restringit per política de l'editorialPredicting the pore pressure distribution in a slope after rapid drawdown conditions requires the solution of a coupled flow‐deformation analysis in a saturated‐unsaturated porous media. A fully coupled finite element code ... -
Rapid drawdown in embankment dams
(CRC Press, 2012)
Capítol de llibre
Accés restringit per política de l'editorialThe calculation of pore water pressure distribution in a slope partially submerged and subjected to a drawdown is analyzed in this chapter. Drawdown phenomenon is a critical situation for the stability of slopes of earth ... -
Recent developments of the Material Point Method for the simulation of landslides
(2015-09)
Article
Accés obertThe 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
(2016-03)
Article
Accés obertOne 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
(CRC Press, 2014)
Text en actes de congrés
Accés restringit per política de l'editorialIn 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 ... -
Simulación numérica de deslizamientos tipo flujo inducidos por licuefacción
(2022)
Text en actes de congrés
Accés obertLos deslizamientos de tierras tipo flujo se caracterizan por recorrer grandes distancias y alcanzar grandes velocidades. La simulación numérica de este tipo de problemas que involucran la dinámica de suelo saturado y no ... -
Slope stability in slightly fissured claystones and marls
(2015-08)
Article
Accés obertThe paper deals with the behavior of some characteristic soft rocks found in the Iberian Peninsula. In geological terms, they belong to Tertiary basins, the Keuper period and the Jurassic-Cretacic transition. The discussion ... -
Slope stability under rapid drawdown conditions
(2009)
Text en actes de congrés
Accés obertThe rapid drawdown condition arises when submerged slopes experience rapid reduction of the external water level. Classical analysis procedures are grouped in two classes: the “stress-based” undrained approach, recommended ... -
Small scale slope failure benchmark test: modelling and prediction
(Elsevier, 2014)
Article
Accés obertA benchmark was designed with the aim of evaluating the capabilities of current modelling techniques and computational codes to reproduce slope failures. Laboratory tests and three instrumented small scale experiments of ... -
Static liquefaction modelling of a landslide with the material point method
(2023)
Text en actes de congrés
Accés obertFlow-like landslides may occur when excess pore water pressures develop in liquefiable materials under saturated or partially saturated conditions, causing rapid movement of the failed mass and long run-out distances. Its ... -
The construction process with the material point method
(International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2023)
Text en actes de congrés
Accés restringit per política de l'editorialThe material point method has become a powerful tool in the geomechanical modelling of large deformation problems and it has been successfully applied in a large number of single and multiphase geotechnical problems involving ... -
The material point method for unsaturated soils
(Thomas Telford, 2015-03)
Article
Accés obertThe paper describes a three-phase single-point material point method formulation of coupled flow (water and air) for hydro-mechanical analysis of geotechnical problems involving unsaturated soils. The governing balance and ... -
The Material Point Method: a promising computational tool in Geotechnics
(2013)
Text en actes de congrés
Accés obertIn recent years, the Material Point Method (MPM) has been applied to a number of geotechnical problems and has been extended to solve coupled flow-deformation problems. The dynamic formulation and the dual description of ... -
Thermal effects in landslide mobility
(Thomas Telford, 2018-06)
Article
Accés restringit per política de l'editorialThe 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
(CRC Press, 2019)
Capítol de llibre
Accés restringit per política de l'editorialThe 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 ... -
Thermo-poro-mechanical analysis of landslides: from creeping behaviour to catastrophic failure
(Thomas Telford, 2015-10)
Article
Accés obertThe scope of the paper encompasses planar and compound sliding motions, which may exhibit creeping behaviour during a certain period but may evolve to a very rapid motion. Thermo-mechanical interactions, at the scale of ... -
Wetting collapse and failure of and slope tested in centrifuge machine
(International Centre for Numerical Methods in Engineering (CIMNE), 2017)
Text en actes de congrés
Accés obertThis paper presents a centrifuge model of a silty clay slope. The increase of the gravity accel-eration is applied to the slope under unsaturated conditions. The slope is wetted in flight by means of water injection from ...
