摘要通过建立弹性支承桩–土耦合模型，考虑桩周土三维轴对称振动，求解得到桩周土振动响应频域解析解。通过傅里叶逆变换得到桩周土振动响应在时域内的半解析表达，并借助有限元分析软件对比验证本文解的合理性。在此基础上，对不同工况条件下的桩–土耦合系统参数进行研究，得到桩周土波动响应的规律，为实际工程测试提供理论支持与指导作用。

Abstract：This study proposed an elastic bearing pile-soil coupled model and obtained an analytical solution of soil around pile in frequency domain considering three-dimensional symmetric vibration of soil around piles. The semi-analytical solution of surrounding soil in time domain can be solved with inverse Fourier transform，and the validity can be proved by compared with the result solved by FEM software. On this basis，parameters of pile-soil coupled system can be analyzed during variable conditions，and laws of dynamic response of surrounding soil can be concluded as well，which can be used to provide practical guidance for engineering application.

Key words： pile foundation low-strain dynamic test integral transform finite element method(FEM)
