The dynamic response of embedded piles under vertical loading
This paper treats the dynamic response of a pile which supports a mass subjected to an oscillating vertical load. We assume the pile is embedded, loosely' with only its base bonded to the surrounding soil material whose special characteristics account for all the energy dissipation. This soil-pile system may be interpreted as a frequency-dependent spring-dashpot model. We model the pile with a standard one-dimensional theory and use full three-dimensional elasticity theory for an approximate embedding half-space. With the aid of Lame potentials and Hankel transforms, integral representations for the effective spring constant and damping coefficient are found. The integrals are evaluated numerically and results are presented over a range of forcing frequencies and or various soil-pile configurations.
