低应变法检测冲孔灌注桩完整性的应用探讨

Discussion on the application of low strain method to test the integrity of bored pile

简述低应变法的方法原理,总结了影响检测的因素及解决办法和冲孔灌注桩的质量缺陷。结合工程实例,采用钻芯法验证检测,能有效解决桩身完整性判定问题,总结了不同缺陷基桩的波形特征。

This paper introduces the principle of low strain method,summarizes the factors affecting the detection,the solutions and the quality defects of bored pile.Combined with an engineering example,the core drilling method is used to verify the detection,which can effectively solve the problem of pile integrity judgment,and summarizes the waveform characteristics of different defective piles.
