钻孔灌注桩浅部缺陷低应变检测实例分析

在钻孔灌注桩施工过程中,如果采取措施不到位尤其是在地质条件差的情况下,容易产生桩身质量缺陷,其中有相当多的缺陷发生在桩的浅部。本文提出了在低应变检测过程中尤其是当桩身存在浅部缺陷时应该注意的几点问题,并通过几个检测实例加以说明。

Case Study of Low Strain Integrity Testing of Shallow Defects of Bored Pile

During construction of bored piles,if the measures are not in place,especially in poor geological conditions,the piles prone to quality defects,and there is considerable defects in shallow parts of the piles.Several problems presented in the text should be given attention in the process of low strain integrity testing especially when there is defects in shallow part of a pile.Which was explained by several testing cases.
