For pile integrity testing for existing structures, the traditional method of reflected waves is no longer applicable. The fundamental principles, field tests and signal analysis of vibration excitation on pile-side are described in detail, which can be well used to test the pile integrity for existing structures, thus providing reference for technical personnel.%对于既有结构下基桩的完整性检测,传统反射波法的激振接收方式不再适用.文中详细介绍了桩侧激振接收法的基本原理、现场检测、信号分析等内容,可以较好地进行既有结构下基桩完整性检测,为相关工程技术人员提供参考.
