低应变动测法检测基桩混凝土离析缺陷

Piles Concrete Isolation Detecting by Low Strain Dynamic Testing

在影响建筑桩基质量的各种缺陷中,混凝土离析比较常见。由于波传播过程中的能量散失等原因,使用低应变法检测混凝土离析较为困难。通过对大量工程实例的分析,总结出低应变动测检测大直径灌注桩混凝土离析缺陷的一些经验,对实际工作有一定的指导意义。

Concrete isolation is an ever-present bug in the perfusion pile. Due to power dissipating,it is very difficult to detect these bugs by low strain dynamic testing.Through many cases analyzing,this paper summarize some useful experience about large diameter concrete perfusion pile s low strain dynamic testing.
