反射波法在有地下水的人工挖孔桩中的检测

Testing of reflection method in manual hole digging pile with ground water

介绍了低应变反射波法的基本原理和分析方法,探讨了低应变反射波法检测在有地下水与无地下水的人工挖孔灌注桩中的差异,并通过工程实例进行了论证。

This paper introduces the basic principle and analysis method of low strain reflection method,discusses the different performances of low strain reflection testing of manually excavated dry-bored piles with or without groundwater and demonstrates them through project cases.
