Abstract
A constitutive model, accounting for multiphase and multiscale coupling, is proposed for the water retention domain and the stress–strain response of compacted clayey soils. The model is based on a conceptual interpretation of the microfabric evolution of compacted soils along generalised hydromechanical paths,
detected by means of mercury intrusion porosimeter tests. Multiphase coupling is provided by the mutual
interaction between the mechanical and the hydraulic states. Multiscale coupling is introduced by a measure
of the size of the aggregates, which influences both the retention and the stress–strain response, in the
phenomenological constitutive equations. Model capabilities are verified by comparison with relevant experimental data from laboratory tests on compacted Boom clay and other selected experimental data on
different compacted clayey soils.
