摘　　要：低应变反射波法测桩是现阶段桩基质量大面积普查中应用最为广泛的无损检测技术。结合太中银客运专线的大量工程实例,根据低应变测试曲线变化特征判断桩身缺陷,在实际测试工作中有利于提高低应变法测桩的准确性。Low strain reflected wave method is the most widely used non-destructive testing technique for large-scale surveyof current-stage quality of pile foundations.This paper,based on engineering practices in Taizhongyin Passenger TransportLine,describes the determination of pile defects according to characters of low strain measurement curves.Thismethod will help improve the accuracy of low-strain method in pile testing in real practices.
