摘　　要：对某工程冲孔灌注桩进行钻芯法检测时,初次钻取的两个孔疑似偏出桩体,通过对其中一个孔进行测斜,结合地质资料、施工记录、低应变法动测进行分析,重新选定开孔位置,再钻芯对该桩完整性进行分析,最后用静载试验验证。本文案例中对钻芯法试验钻孔偏出桩体情况综合运用多种检测、监测方法分析处理,对工程检测中类似问题具有一定的参考价值和意义。When the drilling core method was carried out at a pile of a project, it was suspected that the first drilled two holes was out of pile body. By measuring one of the holes, combined with analysis of geological data, construction records, low strain dynamic measure- ment, the location of the hole was reselected, and then the core was analyzed. Finally, the static load test was applied to verify. In the case of this paper, the various test methods were used to detect the deviation of hole by drilling core test, it has certain reference value and significance to the similar problems in the engineering testing.
