t检验准则检验混凝土芯样抗压强度检测批样本中的异常值

Detection of outliers in inspection lot of estimated strength of concrete with drilled core by t Test Principle

本文针对钻芯确定检测批混凝土强度推定值时个别混凝土芯样强度存在疑问时,阐述应用t检验法准则进行检验判断。通过实例,验证通过该方法,可以使钻芯法结论更为科学,更为严谨性。

Based on the fact that a small number of outlying core specimen are in inspection lot of estimated strength of concrete with drilled core, This paper introduced a method for verifying outlying observations in normal sample based on t Test Principle. Drilling method based on t Test Principle is more scientific and precise through some examples.
