Pile Driving with a Vibro Hammer: Estimating the bearing capacity from vibro driving analysis
Description: While it is a routine practice to estimate the bearing capacity of a pile driven with an impact hammer, this is not the case when the pile is driven with a vibro hammer. Quite often the assumption is that you need to finish pile driving with an impact hammer to get a capacity estimate, but the same process of signal matching can also be applied to vibro driving. In his presentation Verbeek will look at the entire vibro driving process and illustrate the signal matching process through an interesting case study where a pile was mostly driven with a vibro hammer, but then driven to the final penetration with an impact hammer. Signal matching was performed at the end of vibro driving at the beginning of impact driving and then again after some additional hammer blows. This detailed analysis of the monitoring data illustrated that the monitoring of pile driving, and the analysis of the obtained data can and should be the same, irrespective of the hammer type used.
