摘要
现有规程提供了钻芯修正检测混凝土的修正系数法和修正量法两种方法,而确定修正系数和修正量的具体方式有总体、局部和对应测区3种方式。在实际检测鉴定过程中如何合理选择钻芯修正方法,以及如何确定修正系数或修正量的具体方式,是工程师面临的一大难题。本文通过工程实例对钻芯修正法检测混凝土强度的不同方法进行了对比研究。
Two methods of drilled core method, which are revised quantity method and revised coefficient method, are provided in the existing regulations and specifications. Meanwhile general testing zone, local testing zone, and the corresponding testing zone methods are used to determine the revised quantity and the revised coeffi- cient. It is a major challenge for engineers to choose a proper drilled-core method in actual process of inspec- tion and appraisal. In this paer research is done on different methods of drilled-core method using an project example.
