摘　　要：低应变作为基桩动力检测中的一种,因其设备简单、操作方便,被广泛应用于桩身质量普查、桩身完整性类型判别。本文介绍了低应变法的理论及低应变检测的工作机理,剖析了不同桩型下的波形特征,结合工程实际对常见缺陷桩的判别曲线进行分析,为类似工程检测提供参考。Low strain,as a type of dynamic testing for foundation piles,is widely used in pile quality survey and pile integrity type discrimination due to its simple equipment and easy operation.This article introduces the theory of low strain method and the working mechanism of low strain detection,analyzes the waveform characteristics under different pile types,and combines with engineering practice to analyze the discrimination curve of common defective piles,providing reference for the detection of similar projects.

关 键 词：低应变 基桩动力 完整性
