Analysis of impedance function considering soil-pile dynamic interaction

A detailed study of the characters of the soil-pile system’s impedance function,which is the base of the study of the soil-pile dynamic interaction,is carried out in this paper.The contributions of different parameters to the impedance function are derived by the example of single pile.The main parameters which influence the soil-pile system’s impedance function,such as shear wave velocity of different soil layer,radius and length of piles,density of soil and piles,poisson ratio of soil,are suggested.The work is important for the study of the soil-pile-structure interaction.
