Wave Equation - Pile Driving

[NBRY1]

I understand that the wave equation is a method to determine if excessive stresses will occur in a pile and to validate a certain hammer for pile installation. However, can the wave equation also determine target minimum blows to achieve pile capacity?

Yes. It can also calculate an estimated pile length. But remember, GIGO.

I have seen on many cases the prediction was way off. So I tend to trust my judgement rather than the driverability analysis done by an inexperienced engineer (GIGO). You need experience & expertise to get it close to reality. Tricky for driven piles terminating in soils, highly variable rock e.g. basalt.

It also helps to have correct subsurface information.
