| 摘 要： | 低应变动态无损检测法是检测桩基承载力和桩身质量的一项新技术。介绍了低应变动态无损检测法的特点，阐述了该方法的检测原理。通过对反射波的波形、振幅、频谱以及波速与混凝土强度的对应关系分析，从而对桩的质量作出全面评价，该法作为桩基静载试验法的补充，大大提高了经济效益。

| Abstract: | Low strain dynamic nondestructive testing is a new technology to test bearing capacity and quality of pile. In this paper the characteristics of low strain dynamic nondestructive testing are introduced and the testing principle of this method is elaborated. Through the analysis on the corresponding relationships of the wave shape, amplitude and spectra of the reflection wave with strength of concrete the comprehensive evaluations for pile quality are made. This method as supplement of pile foundation static test greatly enhances the economic benefits. |
