摘要
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 concept of estimating interval is provided,and the measurement sampling test batch of compliance with the design requirements is specified in Technical Standard for Inspection of Building Structure(GB/T50344-2004).The origins of estimated interval in GB/T50344 is researched in accordance with One-sided Reliability Confidene Lower Limit(Normal Distribution Complete Sample)(GB4885-85).It is found that the estimating interval and the qualified determination method in GB/T50344 does not match the basic provisions of GB4885.A new estimating interval and a qualified determination method are proposed in the measurement sampling test based on GB4885.
