混凝土强度特征值抽样检测判定的原理与规则

Judgment Principles and Rules of Concrete Strength Eigenvalue in Sampling Test

介绍了混凝土强度特征值的概念,根据混凝土强度概率分布特点和统计学理论阐述了混凝土强度特征值推定区间的原理,并结合国内外相关规范对使用上限判定规则的条件予以说明。最后简要介绍了混凝土强度检测与推定方法应改进与完善之处。

Introduced the concept of concrete strength eigenvalue, elaborated the principle to get interval estimation of concrete strength eigenvalue by the feature of concrete strength probability distribution and theory of statistics. According to interrelated standard home and abroad, explained conditions to use determine rule of upper limit. At last, briefly introduced the part that should be improved in the testing and estimating method of concrete strength.
