Abstract
This paper presents a laboratory study which aimed at investigating the soil/pile interaction during driving. A short review of past experimental works justifies the need for more consistent data. The test equipment (a rod driven through a sample of soil) is briefly presented and some signals are displayed to illustrate the quality of the measurements. The tests were performed on samples of normally consolidated Kaolinit clay. The analysis of the stress waves propagating in the rod, during driving, provided a good estimation of interaction forces, bar velocities and displacements of the pile model in the sample. Relationships were established between the interaction force, the energy dissipated in the sample of soil, the velocity and the displacement of the rod, and the confining pressure of the sample. Observations and relationships were used (1) to identify the physical phenomena occurring at the soil/pile interface during driving, and (2) to base a law governing this shaft interaction.
