回弹—钻芯综合法检测长龄期大批量混凝土强度的应用

回弹-钻芯综合法在工程检测中具有良好的发展前景,工程应用中在不过多增加检测工作量条件下,能大大提高检测数据的可信度。文章应用回弹-钻芯综合法检测长龄期大批量结构混凝土强度,采用误差理论对钻芯检测数据进行处理,计算出局部修正量,并用于修正回弹结果;进一步对局部修正量法和各种回归方法进行分析比较,得出局部修正量法是利用钻芯结果修正回弹值的最优方法。

The Application of Rebound-coring Synthetic Method for Testing of Strength of Long-age Mass Concrete

Rebound-coring method in engineering testing has good prospects for development. Under the condition without excessively increase work load in engineering applications,the method can greatly increase the reliability of testing data. The article adopts rebound-coring detection for testing of strength of long-age mass concrete,processes coring testing data adopting the error theory,calculates the partial correction for amendments to rebound results,and makes further analysis and comparison to partial correction method and various regression methods,to obtain the optimal method for the corrected rebound value using coring results.
