通过对“钻孔灌注桩标养试块抗压强度不合格，而钻芯取样检测合格”现象的分析探讨，得出水下混凝土灌注桩现场抽取试块的抗压强度一般低于桩身，二者间由于密实度的不同，存在着一个修正系数，试块的抗压强度乘以该修正系数后再判定桩身强度较为合理。

The compressive strength of standard curing test block of bored piles is unqualified,but the compressive strength of the piles core samples is qualified. According to the analysis and exploratory of the phenomenon, the following conclusions can be drawn: the compressive strength of spot-check test blocks of underwater concrete is lower than that of the pile body of bored piles, and there is a correction factor between the two compressive strengths because of the compactness difference, and it’s reasonable to determine the strength of pile basing on the correction factor.
