摘　　要：本文从结构混凝土芯样钻取、加工和试验过程,分析了钻芯法检测混凝土抗压强度的主要影响因素,提出了钻芯法检测混凝土强度不确定度的评定方法,并结合工程应用,引入不确定度对结构混凝土强度合格性评定进行了探讨。The main impact factors on the concrete compressive strength detected by the core drilling method are analyzed herein from the processes of the drilling, processing and testing of structural concrete core samples, and then a method of the assessment made on the uncertainty of the concrete strength detected with the core drilling method is put forward. Moreover, the introduction of the uncertainty into the conformity assessment of the structural concrete strength is also discussed in accordance with the actual engineering application concerned.
