摘　　要：根据JGJ/T 152—2019《混凝土中钢筋检测技术规程》中的检测技术要求,对同一点混凝土剪力墙钢筋保护层厚度进行10次重复性检测,综合分析相关标准检验检测过程以及日常检测过程,建立数学模型,进行不确定度分量的确定。依据JJF 1059.1—2012《测量不确定度评定与表示》进行A类不确定度和B类不确定度计算,最终得到钢筋保护层厚度的测量不确定度,保证日常检验检测活动的准确性,维持实验室的不确定度评价能力。According to the testing technical requirements in JGJ/T 152—2019"Technical Standard for Test of Reinforcing Steel Bar in Concrete",the concrete cover depth of shear wall at the same point was repeatedly tested for 10 times,and the relevant standard measuring process and daily measuring process were comprehensively analyzed to establish mathematical model and determine the uncertainty component.According to JJF 1059.1—2012"Evaluation and Expression of Uncertainty in Measurement",Class A and Class B uncertainties are calculated,to ensure the accuracy of daily measuring activities and maintain the uncertainty evaluation ability of laboratories.
