摘要
低应变法由于快速、经济、简便,在基桩检测中得到了广泛的应用,但其无法准确判定桩身缺陷的严重程度,由此提出对基桩分别进行高、低应变检测,并通过对测试结果的综合分析,较准确地判定桩身缺陷以及严重程度。通过多个工程验证,此方法在基桩检测中具有很好的应用前景。
Low strain integrity testing is widely adopted for fast, economical and convenient in the foundation pile testing, which can＇t confirm the grade of pile defects. It is suggested to perform the low strain integrity testing and high strain dynamic testing respectively on the same pile and evaluate the grade of pile defects according to the test results. It is useful for the foundation pile test through several projects.
