摘　　要：任何测量都可以用被测量之值的最佳估计值和测量不确定度两部分来准确表达。本文从影响钻芯法检测混凝土抗压强度的几个关键影响因素入手,分析其给抗压强度测试结果带来的不确定度分量,并进行不确定度合成,从而得到利用不确定度来表达的钻芯法抗压强度测量值。Any test can be expressed with two parts - the optimum estimated value and test value uncertainty of the tested value. In this article, the analysis was made on the uncertainty component from compressive strength test result by means of several key influence factors which involve in concrete compressive strength test with drilled core method, and the composition of uncertainty were also done so as to achieve the compressive strength value with drilled core method represented by uncertainty,
