Abstract:The vibration test is more than an integrity test because it also gives a measurement of soil-pile interaction. Of particular importance is the measurement of pile head stiffness E', which is a dynamic measurement of the initial load settlement characteristic of the pile. It is useful to plot pile head stiffnesses of a population of piles of similar dimensions on a site where the geological profile is fairly uniform. Fig. 18 shows what was done on a site at Rossano de Calabro in southern Italy where 730 piles … Show more
