摘　　要：对考虑桩土系统动力相互作用时的阻抗函数进行了细致的分析,以单桩为例导出了各参数对整体阻抗函数的贡献,明确了影响桩土系统动力相互作用阻抗函数的各种主要参数,如各层土的剪切波速;桩的半径和长度;土与桩的密度;土的泊松比等,为进一步研究桩土结构相互作用打下基础。A detailed study of the characters of the soil-pile system＇s impedance function, which is the base ot the study of the soil-pile dynamic interaction, is carded 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.
