The paper presents a numerical model for the kinematic interaction analysis of inclined pile groups; piles are modelled with beam finite elements and the soil is schematized with independent horizontal infinite layers. The pile-soil-pile interaction and the radiation problem are accounted for by means of elastodynamic Green’s functions. A rigid constraint is introduced to account for the pile cap and the problem condensation allows obtaining the dynamic impedance matrix of the soil-foundation system The model is validated comparing results, in terms of dynamic impedances, with those furnished by 3D refined finite element models.

Abstract

The paper presents a numerical model for the kinematic interaction analysis of inclined pile groups; piles are modelled with beam finite elements and the soil is schematized with independent horizontal infinite layers. The pile-soil-pile interaction and the radiation problem are accounted for by means of elastodynamic Green’s functions. A rigid constraint is introduced to account for the pile cap and the problem condensation allows obtaining the dynamic impedance matrix of the soil-foundation system The model is validated comparing results, in terms of dynamic impedances, with those furnished by 3D refined finite element models.
