国家标准《建筑结构检测技术标准》(GB/T50344-2004)中给出了推定区间的概念,并规定了计量抽样检测批符合设计要求的评定方法。本文按《正态分布完全样本可靠度单侧置信下限》(GB4885-85)的要求,探究了GB/T50344中推定区间的来历,指出了GB/T50344关于推定区间及合格判定方法与GB4885基本规定不相符合之处,提出了基于GB4885的计量抽样检测批推定区间和合格判定的新方法。
The national standard “Technical Standards for Testing Building Structures” (GB / T50344-2004) gives the concept of estimation interval and specifies the assessment method that meets the design requirements. According to the requirement of “the lower limit of one-sided confidence limit for the reliability of complete samples with normal distribution” (GB4885-85), this paper explores the origins of the estimated interval in GB / T50344, points out the basic provisions of GB / T50344 about the estimation interval and conformity determination methods and GB4885 Do not match the place, proposed based on the GB4885 batch sampling and testing batch of approved the determination of a new method of pass.
