目前,国内外的强度验收主要是通过为数不多的、从拌和机口取出的样本强度,并根据相应的标准,对工程或结构物的混凝土质量进行评定。因此,如何制定一个合理而经济的质量验收标准,是直接关系到工程或结构物的安全是否能得到保证的关键。而抽样检验的理论正是制定这种验收标准的依据。抽样检验理论的内容是极为丰富的,因篇幅所限,本讲仅就与混凝土质量验收标准有关的数理统计基本概念加以介绍。掌握了这部分内容,可以帮助我们理解目前国内外
At present, the strength acceptance at home and abroad is mainly through the small sample strength extracted from the mixing machine mouth, and according to the corresponding standards, the concrete quality of the project or structure is evaluated. Therefore, how to develop a reasonable and economical quality acceptance standard is the key to whether the safety of the project or structure can be guaranteed. The theory of sampling inspection is the basis for formulating such acceptance criteria. The content of the sampling inspection theory is extremely rich. Due to limited space, this lecture will only introduce the basic concepts of mathematical statistics related to concrete quality acceptance standards. Having mastered this part of the content can help us understand the current domestic and international
