摘　　要：本文讨论了采用不同标准规范下的混凝土芯样合格判定的条件,以工程实例分析了钻芯检测结果,建议标准芯样、高径比修约系数、直径修约系数、合格判定条件等统一起来,以便工程技术人员更好地掌握使用。This paper discusses the conditions for judging the qualification of concrete core samples under different standards and codes,analyzes the test results of drilling core with engineering examples,and suggests that the standard core samples,the reduction coefficient of height diameter ratio,the reduction coefficient of diameter,and the qualification judging conditions should be unified,so that the engineering technicians can better master and use them.

关 键 词：芯样 强度 合格
