Degradation effects at microstructural scale and their consequences on macroscopic behaviour of a slightly weathered siltstone.
(CRC Press/Balkema, 2010)
Conference lecture
Restricted access - publisher's policyA 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
(CRC Press, 2009)
Part of book or chapter of book
Restricted access - publisher's policyThis 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
(2009)
Conference lecture
Open AccessThe 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
(IOS Press, 2011)
Conference report
Restricted access - publisher's policyA 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
(2008)
Conference report
Open AccessThis 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
(2009)
Conference report
Open AccessThe 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
(Taylor & Francis, 2010)
Conference lecture
Restricted access - publisher's policyThis 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.
(2011)
Conference lecture
Restricted access - publisher's policyThe 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 ...
