How to Select Piling Vibratory Hammer?

To form sheet pile retaining wall, we need vibratory hammer to drive piles into the soil. Then how to select the hammer?

Vibratory hammer selection should meet three basic conditions :

1) Excitation force of vibratory hammer P0 should be equal to or greater than the sinking components being vibrated and soil’s dynamic lateral friction Tv ;

2) The total weight of vibratory hammer system Q0 should be greater than the driven components’ dynamic tip resistance Rv ;

3) Work rate of vibratory hammer system A0 should be greater than the minimum required amplitude A0 when driven components go through soil layers.
