摘　　要：为了对“桩－土”非均质系统的弹性动力响应进行研究，根据桩侧土的非均匀性以及桩结构的缺陷特征，建立了一个“桩－土”非均质系统的动力学模型，并导出了其数值解。并以模型桩为计算实例，通过计算结果与实测曲线的对比，识别出桩土参数，用于评价桩结构的完整性。To study elastic dynamic response of `pile-soil' non-homogeneous system, a dynamic model of `pile-soil' system is established by considering non-homogeneous soil around piles and pile structure's defects, and a numerical solution is derived. Several applicable examples of model pile are given by using the numerical method. The parameters of `pile-soil' system are identified by comparing the calculating results with the test results, to examine the structure integrity in a pile.
