机械阻抗法适用于检测桩身混凝土的完整性,推断桩身缺陷及其位置;当有可靠的同条件动静对比试验资料时,还可用于推算单桩承载力.但机械阻抗法检测混凝土桩的基桩质量时,对桩身缺陷程度和入岩情况只能做定性判定,而取芯法可以很大程度补充机械阻抗法的不足.

It is proved that mechanical impedance method can be applied to the detection of concrete pile integrity,and the inference of the pile defect and its position.When there are enough reliable verifying data with dynamic-static contrast,the mechanical impedance method can also be used to calculate the bearing capacity of single pile.But when the method is used to determine the quality of the piles,it can only submit qualitative analysis of the defect degree and the circumstance of pile rooting.While the coring method is used at the same time,the more details can be given,and the insufficiency of mechanical impedance method can well be complemented.
