dc.description.abstract | The Guadalquivir blue marl is a high plasticity overconsolidated carbonate clay. This soil
presents an elevated fragility and high susceptibility to moisture changes. These characteristics have caused
many geotechnical accidents, such as the Aznalcollar dam failure, in Seville (Spain). A comprehensive test
campaign has been conducted to determine the physical and chemical properties of the blue marl. Analysis
by scanning electron microscopy (SEM) and mercury intrusion porosimetry (MIP) allowed characterising
its internal structure, revealing clear differences between the macro and the microstructure. A novel model
for predicting the volumetric deformation (under oedometric conditions) of the Guadalquivir blue marl with
suction and vertical pressure changes has been proposed. The model, based on data from shrink-swell tests,
provides an acceptable estimation of the volumetric behaviour of the soil with a relatively simple set of
parameters. The results were experimentally verified by suction-controlled oedometer tests and showed an
acceptable agreement with the data measured. It has been specified when swelling. shrinkage or collapse
occur. | es |
