is the SPT-N value at the pile base calculated using the following equation: N = 0.5(N 1 + N 2) Where N 1 is the smallest SPT-N values over the two effective diameters below the toe level N 2 is the average SPT-N value over 10 effective diameters below the pile toe. It should be noted that, for submerged sands, the SPT-N value needs to be ...

Fundamentals of the vibratory driving of piles and sheet piles

tage of modern vibrators is that machine parameters can be varied to achieve efficient driving or compaction. Vi-bratory excitation affects a pile in a different way to im-pact driving. In the case of vibratory driving, the pile is rigidly connected to the vibrator, resulting in minimal en-ergy loss as energy is transferred from vibrator to ...
