摘要
《混凝土强度检验评定标准》(GBJ 1 0 7- 87)的主要问题 ,一是偏宽 ,达不到设计要求的强度等级 ;二是强度合格评定采用的三种方法 ,宽严不一致 ,且都有不合理之处。本文加以评析 ,并提出应统一按标准差已知、以总体均值衡量的一次计量抽样检验方案来制订混凝土强度合格评定标准。
The main problems existing in <The Test and Evaluation Standard of Concrete Strength>(GBJ 107-87)are:1)it is too loose and does not reach the design required strength class;2)the three methods which are adopted are of different strictness and they have unreasonable aspects.This paper evaluates and analyzes the problems and proposes the single sampling plan by variables to build the qualification standard of concrete strength.The plan is based on that the standard deviation is set and is measured by total mean strength.
