Degradation effects at microstructural scale and their consequences on macroscopic behaviour of a slightly weathered siltstone.
Pineda, Jubert Edgar; Romero Morales, Enrique Edgar; Gómez, Susana; Alonso Pérez de Agreda, Eduardo (CRC Press/Balkema, 2010)
Comunicació de congrés
Accés restringit per política de l'editorialA systematic experimental programme was performed on a slightly weathered siltstone of Weald facies (Cretaceous period) to study the degradability of the material due to hydraulic and mechanical processes. The paper ... -
Degradation of partially saturated argillaceous rocks: influence on the stability of geotechnical structures
Pineda, Jubert Edgar; De Gracia, M; Romero Morales, Enrique Edgar (CRC Press, 2009)
Capítol de llibre
Accés restringit per política de l'editorialThis paper presents the results of an experimental programme aimed at evaluating the degradation phenomena of an argillaceous rock due to the application of hydraulic cycles. The degradation of shear strength parameters ... -
Effects of heating and hydraulic cycling on the stiffness response of a rigid ansiotropic clay: preliminary results
Mitaritonna, Giuseppina; Pineda, Jubert Edgar; Romero Morales, Enrique Edgar; Arroyo Alvarez de Toledo, Marcos (2009)
Comunicació de congrés
Accés obertThe poster presents the results of an experimental investigation aimed at evaluating the effects of heating and hydraulic cycling on the small-strain stiffness of a rigid Jurassic clay (Opalinus clay, Jura Mountains, Mont ... -
Foundation of a gravity dam on layered soft rock: shear strength of bedding planes in laboratory and large “in situ” tests
Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè; Pineda, Jubert Edgar (IOS Press, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialA 100 m high gravity dam (Castrovido dam, Burgos, Spain) is founded on a soft Weald red siltstone with interbedded sandstone strata. Dam stability is essentially controlled by the available shear strength of sedimentation ... -
Low-strain shear modulus dependence on water content of a natural stiff clay
Lima, A; Romero Morales, Enrique Edgar; Pineda, Jubert Edgar; Gens Solé, Antonio (2008)
Text en actes de congrés
Accés obertThis paper shows the results of an experimental programme aimed at evaluating the low-strain shear modulus of a stiff clay (Boom clay, Belgium) and its dependency on water content changes (or, alternatively, degree of ... -
The effect of drying-wetting cycles on the seismic properties of an anisotropic claystone
Mitaritonna, Giuseppina; Pineda, Jubert Edgar; Arroyo Alvarez de Toledo, Marcos; Romero Morales, Enrique Edgar (2009)
Text en actes de congrés
Accés obertThe evolution of bar and shear wave velocities during a drying wetting cycle on a claystone is presented. There is a clear relationship with total suction, established by means of the material water retention curve. The ... -
Thermal pulse effects on the stiffness degradation of unsaturated clayey materials
Lima, Analice; Pineda, Jubert Edgar; Romero Morales, Enrique Edgar (Taylor & Francis, 2010)
Comunicació de congrés
Accés restringit per política de l'editorialThis paper describes the results of an experimental programme carried out to evaluate the influence of relatively fast thermal pulses on the stiffness degradation of two Tertiary argillaceous rocks (a plastic clay rock and ... -
Tracking degradation of argillaceous rocks using bender elements.
Pineda, Jubert Edgar; Romero Morales, Enrique Edgar; Alonso Pérez de Agreda, Eduardo (2011)
Comunicació de congrés
Accés restringit per política de l'editorialThe results of a comprehensive experimental program focused on the study of progressive degradation processes on a low permeability argillaceous rock induced by hydraulic cycles is presented in the paper. Relative humidity ...
