摘　　要：在工程建设中,对地下基桩的无损检测常采用应力波法、声波透射法、抽芯法、磁测井法等单一方法。以江苏省盐城市某住宅小区地库工程桩基检测为依托,选用低应变动测法、磁梯度法检测组合进行分析,得出了合理的检测结论,消除了工程潜在的隐患,证明了采用多种检测方法组合的必要性,为类似工程基桩质量检测提供借鉴和参考。In engineering construction,single methods such as stress wave method,acoustic wave transmission method,centrifugal method,and magnetic logging method are often used for non-destructive testing of underground foundation piles.In the pile foundation detection of a basement project in a residential community in Yancheng,Jiangsu Province,the combination of low strain measurement and magnetic gradient method was selected as a case,and a reasonable detection conclusion was drawn to eliminate potential hidden dangers in the project.This proves the necessity of using a combination of multiple detection methods,and provides a reference and reference for the quality inspection of similar engineering foundation piles.
