关于《回弹法检测混凝土抗压强度技术规程》推定系数和抽样方案的统计原理分析

Analysis on Technical Specifications for Inspections of Concrete Compressive Sthrength by Rebounded Method

本文根据数理统计原理及《计量标准型一次抽样检验程序及表》(GB/T 8054—2008)等系列规范,对《回弹法检测混凝土抗压强度技术规程》(JGJ/T 23-2011)推定系数和抽样方案(n,k)进行了分析。计算分析得到现行规范的抽样方案(10,1.645)生产方风险达到50%,对生产方要求过严格。经过计算分析,建立单个构件评定采用(10,1.5),批量检测采用(44,1.3)的抽样方案较为合理。

The paper analyzed presumption coefficient and sampling plans（ n,k） in single sampling procedure and tables for inspection having desired operating characteristics by variable（ GB/T 8054—2008） based on mathematical statistical principle and single sampling procedures,tables for inspection having desired operating characteristics by variables（ JGJ/T23-2011） and other specifications. The results showed that the manufacturer＇s risk of the current specification sampling plan（ 10,1. 645） reached 50% which was strict with the producers.. It was reasonable to establish a single component evaluation（ 10,1. 5） and panel testing（ 44,1. 3） after calculation and annlysis.
