在基桩检测中,对桩身缺陷的错误判断往往给工程造成安全隐患.结合工程实例分析低应变法检测对桩身缺陷位置判断的局限性,得出结论:低应变法可以较准确判断桩顶下第一个缺陷的位置,有效测试长度为桩顶至桩底或第一个严重缺陷位置.提出工程检测中对低应变法发现的浅部缺陷,通过开挖的方式进行验证,并在工程处理后再次用低应变法对余下部分基桩进行完整性检测.
在基樁檢測中,對樁身缺陷的錯誤判斷往往給工程造成安全隱患.結閤工程實例分析低應變法檢測對樁身缺陷位置判斷的跼限性,得齣結論:低應變法可以較準確判斷樁頂下第一箇缺陷的位置,有效測試長度為樁頂至樁底或第一箇嚴重缺陷位置.提齣工程檢測中對低應變法髮現的淺部缺陷,通過開挖的方式進行驗證,併在工程處理後再次用低應變法對餘下部分基樁進行完整性檢測.

The potential for security problems were sometimes caused by the leakage judgment of pile defects in pile foundation detection. Combined with the practical engineering detection and analysis of low strain integrity test in pile defect missing,this paper concluded that the first defect position could be judged accurately and the bottom of pile or the first serious defect position could be tested,and proposed the shallow defects found by the low-strain integrity test could be verified by the excavation way in the detection of engineering,and low-strain integrity test could also be used to test pile integrity after the treatment.
