A model for rockill compressibility
(Institution of Civil Engineers (http://www.ice.org.uk/), 2001)
Article
Accés obertThe paper presents a macroscopic constitutive model for rockill that includes the effect of water on compressibility and collapse phenomena. Breakage of rock particles and fracture propagation are basic underlying mechanisms ... -
Characterisation and thermo-hydro-mechanical behaviour of unsaturated Boom clay: an experimental study
(Universitat Politècnica de Catalunya, 1999-09-08)
Tesi
Accés obertEl objetivo principal de esta investigación se centra en el análisis de los efectos de la temperatura y la hidratación o secado de las arcillas en el comportamiento de cambio de volumen, permeabilidad y características de ... -
Chemo-hydro-mechanical behaviour of compacted Boom Clay: joint effects of osmotic and matric suctions
(Thomas Telford, 2014-07)
Article
Accés restringit per política de l'editorialAn experimental programme involving osmotic and matric suction controlled tests is carried out to investigate the effects of increasing pore fluid concentration, chemical cycling (salinisation/dilution) and matric suction ... -
Experimental investigation on an effective stress law in compacted clayey/silty soil
(2011)
Text en actes de congrés
Accés restringit per política de l'editorialExperimental results of isotropic stress tests performed on statically compacted clayey silt are presented to examine the volume change response of the material subjected to controlled increments in net mean stress and ... -
Hydro-mechanical behaviour of water-repellent gravels
(Universitat Politècnica de Catalunya, 2017-01-25)
Projecte Final de Màster Oficial
Accés obertEl comportamiento de escolleras y gravas ha sido ampliamente estudiado debido al gran número de aplicaciones de estos materiales en ingeniería civil. Las escolleras experimentan una deformación de colapso bajo carga ... -
Hydromechanical behaviour of compacted granular expansive mixtures: experimental and constitutive study
(2011-04-01)
Article
Accés restringit per política de l'editorialCompacted granular mixtures of high-density bentonite pellets have been evaluated as an alternative buffer material to fill the empty space around nuclear waste disposal canisters in horizontal drifts. Despite the obvious ... -
LED lamp modelling for harmonic studies in distribution systems
(2017-03-09)
Article
Accés restringit per decisió de l'autorEnergy saving policies have boosted the use of light emitting diode (LED) lamps in distribution networks. These lamps are non-linear loads which inject harmonic currents into the distribution system, which has led to a ... -
Shear strength degradation in claystones due to environmental effects
(Thomas Telford, 2014-05)
Article
Accés restringit per política de l'editorialThis note explores the influence of environmental effects, as those induced by cyclic changes in relative humidity, on the degradation of the shear strength parameters in Lilla claystone, a low-porosity clayey rock from ... -
Small strain shear moduli of unsaturated natural and compacted loess
(Thomas Telford, 2017-07)
Article
Accés obertSuction and microstructure play critical roles in the mechanical behaviour of loess, yet their effects on small strain (from 0·001 to 1%) shear moduli are not fully understood. In this study, shear moduli of loess with ... -
Swelling behaviour of compacted Maryland clay under different boundary conditions
(Thomas Telford, 2019-06)
Article
Accés obertThis paper presents an experimental study on the swelling response of compacted Maryland clay specimens subjected to hydration under a range of boundary conditions. The research is multi-scale with swelling tests complemented ...
