钻孔灌注桩完整性检测的综合应用

Bored pile integrity testing of integrated application

针对灌注桩桩身质量检测时单一的检测方法可能无法全面反映桩身缺陷,容易发生漏判、误判的现象,提出了将超声波法、低应变法、钻孔取芯法等综合应用于桩身完整性检测中,并结合实例作了详细论述,以期对桩身混凝土质量做出正确的评价。

In light of bored pile quality detection defects including single examination methods, incomplete pile defects, identifying failures and errors, the paper puts forward pile integrity detection method by applying ultrasonic wave, low strain method and drilling-coring method, and makes specific discussion by combining with examples, with a view to make a correct evaluation of pile concrete quality.
