摘要
钻芯法评定混凝土的强度,是国际上比较认可的方法,但是该方法存在着一定的局限性;同时鲜有检测单位对数据异常值进行判断并采取措施进行处理,制约混凝土强度评定的准确性。本文对各种误差进行分析并以工程实例进行了异常数据的判断和处理。
Core drilling method to assess the strength of concrete is relatively recognized in the world,but it has some limitations. At the same time, the phenomenon of almost no test department to judge data outliers and take follow-up measures restricted the accuracy of concrete strength evaluation. In this paper, the various errors were analyzed and some methods of judgment and processing of abnormal data will be introduced with engineering examples.
