This paper presents results of documented soil motions in the ground based on full scale field tests of vibro-driven sheet piles. A novel simplified analytical view of the transfer mechanisms is presented for singular and in interlock driven sheet piles, describing the dynamic vibro-pile-soil-interaction at shaft as well at pile toe. The view comes out of experiences from numerous conducted field tests, based on a range of different results from self-developed sensors that's been mounted; on the driven piles, left in place on preinstalled piles, on- and in-depth of the soil at different radial distances in the soil volume beside the driven pile. The vibration transfer to soil at the pile-soil interface boils down to the pile motion. The motion of the pile is a consequence of how the driving force enters the driven profile. Results of infield observed soil motion are presented, the effects of how the pile vibrates both vertically, horizontally as well as transversally and how the motion of the driven profile connected to the adjoining sheet pile wall, is set into motion as well and therefore also transfers vibrations into the nearby soil.
