A device for static and/or dynamic identification tests on foundation piles
This work describes the design and construction process of an experimental device for static and/or dynamic identification tests on foundation piles. The aim is to provide information on the behaviour of soil-pile systems subject to seismic action. The primary objective is the validation of numerical models currently available for research purposes pointing out inevitable shortcomings and outlining aspects that should be investigated in detail in the near future. In this respect this paper is closely related to a companion one on numerical aspects published in this same volume. The device is specifically designed for the application of horizontal forces and couples to pile heads. Besides the evaluation of the limiting values of dynamic parameters, generally speaking stiffness and flexibility coefficients, static tests have the objective of identifying the viscoelastic behaviour of the system through creep tests. The experimental tests carried out by means of this prototype device will provide an opportunity to gather information not only on the global behaviour of the soil-pile system but also on the strain and stress state within the pile stem and indirectly within the soil.
