不同检测方法在桥梁工程混凝土强度检测中的对比分析

Comparative analysis of different detection methods in concrete strength testing of bridge engineering

文章对比研究回弹法、超声回弹综合法和钻芯法在桥梁工程混凝土强度检测中的应用,结果表明,回弹法、超声回弹综合法的检测结果与钻芯法检测结果之间并无固定大小关系;同一构件中,回弹法在检测侧面混凝土强度时的误差范围更小,而超声回弹综合法在检测底面混凝土强度时的误差范围更小。

This article compares and studies the application of rebound method,ultrasonic rebound comprehensive method,and core drilling method in concrete strength testing of bridge engineering.The results show that there is no fixed size relationship between the testing results of rebound method,ultrasonic rebound comprehensive method,and core drilling method;in the same component,the rebound method has a smaller error range in detecting the strength of the side concrete,while the ultrasonic rebound comprehensive method has a smaller error range in detecting the strength of the bottom concrete.
