| 摘 要： | 针对现有锚杆质量检测方法存在检测具有破坏性、检测过程复杂、检测精度不高等问题,提出一种基于磁致伸缩导波技术的锚杆无损检测新方法.在研究磁致伸缩导波检测原理以及锚杆中导波特性的基础上,研制了锚杆检测系统,并利用该系统在锚杆中激励出L(0,1)模态导波,完成了空气中以及混凝土结构中锚杆长度以及缺陷的检测实验,实现了对锚杆的非接触式无损检测.结果表明:该方法检测过程简单、检测精度高,能检测具有隐蔽性的锚杆等,可以实际应用在锚杆质量检测中. |

| Abstract: | Traditional rockbolt testing methods have problems of destruction to the rockbolt,complex testing process and low detection accuracy.In view of those problems,a new nondestructive testing method based on magnetostriction guided wave was proposed.On the basis of studying the magnetostriction guided wave theory and the characteristics of guided wave in rockbolts,a testing system was developed.Guided waves of L(0,1) mode were excited in rockbolts by the testing system.Experiments of detecting the length and de... |
| Keywords: | magnetostriction guided wave rockbolt nondestructive testing(NDT) |
