Sommario This paper presents the results of lateral impact load field tests carried out on three steel pipe piles at the tourist port of La Spezia, Italy. The piles are vibro-driven into marine soft clay, with a L-shaped plan layout, kept free at the head. Two test campaigns are carried out, the first 1 week and the second 10 weeks after vibrodriving of the piles. The dynamic behaviour of the complex soilwaterpile system at very small strain is discussed. In particular, the response of the single pile and the mutual interaction between loaded and receiver piles are presented. The variation in dynamic behaviour of the whole system in time (for the two campaigns), due to reconsolidation of the soil close to the pile subsequent to the vibrodriving, is observed. The experimental data are compared with the results obtained from a 3-D finite element models of the whole soilwaterpile system considering both a solid and a shell model for the piles and linear behaviour for the soil.
