Assessment of Dynamic Stability of Foundations on Saturated Sandy Soils

This paper deals with the dynamic analysis of foundations in saturated soils. In the first part, a mathematical formulation is briefly outlined in which soil is considered as a two-phase medium comprising the soil skeleton and voids filled with a viscous fluid. Such formulation is suitable for describing a solid-fluid transition associated with the liquefaction phenomenon. Subsequently, the notion of dynamic stability is reviewed and a simple …
