The driving resistance of a vibro-driven pile is analyzed by establishing a dynamic force equilibrium between the vibratory exciter force, the inertia forces, and the soil resistance as a function of time for a rigid body type of pile vibration. The driving resistance has a periodic variation and depends on the vibratory velocity of the pile.
