摘要

The description, equipment, and results of a series of pile-driving experiments conducted in a centrifuge using a model pile driven in dry sand are included in the report. The works was conceived on the basis of the modelling of a soil-structure system under an artificially generated gravitational field, and motivated by the need for experimental data for a better understanding of the complex phenomena involved in the pil-soil interaction during driving. The behavior of the pile itself has been the focus of more attention in the past, but few full-scale or model experimental results have been obtained to the present concerning the soil stress field during pile driving. These are necessary for comparison with analytical and theoretical work. The objective was to obtain a good understanding of the physical phenomena occuring in the soil and pile during driving. The relations between static and dynamic data were explored, which resulted in the modelling of the soil-transducer interaction with a non-linear, history-dependent, model.
