摘　　要：高应变动测法基于自身高效性和准确性,被广泛应用在基桩检测中。文中叙述了高应变的检测机理以及参数选取,明确了不同工况下桩基波动方程,在此基础上结合实际工程,给出了高应变动测法的检测步骤,结合实际荷载-位移曲线,验证了该方法的准确性,可为相关工程提供参考。High strain dynamic testing method is widely used in pile detection because of its efficiency and accuracy. This paper describes the detection mechanism of high strain and the selection of parameters, and defines the wave equation of pile foundation under different working conditions. On this basis, combined with the actual project, the detection steps of high strain dynamic measurement method are given. Finally,combined with the actual load displacement curve, the accuracy of this method is verified, which provides a reference for related projects.
