ABSTRACT
This chapter describes how it is possible, starting from simple material models that are incapable of accounting for the characteristics of intermediate soils such as Venetian silts mixed with sand and/or clay, to use a set of constitutive laws that account for the ratio of granular to cohesive material to describe the behavior of ‘transitional’ soils with similar mineralogy in a one-dimensional compression model.
The model is based on an elastoplastic constitutive approach developed for cohesionless soils that here has been combined with a two-phase granular inclusions/clay matrix conceptual approach, in order to describe the compression behavior of transitional soils through a single framework.
This chapter describes the one-dimensional constitutive model and its application to the prediction of settlements in highly heterogeneous soil conditions such as that typical of the subsoil at the lagoon inlets.
