回弹法钻芯修正偏差量离群值Grubbs检验

摘要

当采用钻芯法修正回弹法检测结果时,如对芯样试件抗压强度值与对应回弹法测区强度换算值的偏差存在疑问时,可采用格拉布斯(Grubbs)检验法对偏差量离群值进行判断.本文通过实例分析,验证该方法的正确性、严谨性.%When there are doubts about the individual data of rebound correction core deviation correction,the correction deviation outlier can be judged and handled based on Grubbs criterion.Through examples,the correctness and rigor of the method was verified.
