摘　　要：对我国现行规范中涉及钻芯检测及推定检验批混凝土强度值的方法进行比较和分析,并结合实际工程案例进行说明,在此基础上针对既有建筑安全性鉴定中的钻芯检测并评定检验批混凝土强度值的方法提出建议,以期弥合既有建筑现场钻芯时遇到的实际困境与规范要求之间的差距。This paper compares and analyzes the drilled core methods and presumption of concrete strength of inspection lot in the current Technical code of our country,and explains it with practical engineering cases.On this basis,some suggestions are put forward for the method of drilled core and evaluating the concrete strength of inspection lot in the existing building safety appraisal,in order to bridge the gap between the actual difficulties in drilling core of existing buildings and the requirements of the code.

关 键 词：钻芯法 混凝土强度 既有建筑 批量推定
