摘　　要：低应变检测和静载试验是两种不同的桩基检测方法,但却能从不同角度反映桩基的施工质量,因此结合两种检测方法能有效地分析施工过程中的缺陷。结合一实际工程,采用此方法分析了载体桩施工质量不合格的原因,并提出了采用此方法对工程桩进行分类处理,最终进行处理后工程桩的质量验收。经过检测证明,该方法对处理载体与桩身结合不良的缺陷非常有效。Although low strain testing and static load testing are two different testing methods, which can indicate the quality of construction in different ways. So with the combination of two testing methods, the defect of pile during construction can be analyzed. Based on a real engineering with the combination of low strain testing and static load testing, the reason of defect during construction was analyzed effectively. The method to classify and treat the pile was put forward, and it was also used to test the quality of pile after treatment. The testing indicates that the method is effective to treat the defect between shaft and bearing base.
