摘　　要：从锚杆锚固质量无损检测技术发展现状出发,阐述了现有检测中的不足,指出了锚固系统砂浆饱满度检测的重要性,并创新性地将Hilbert变换与Wigner-Ville分布信号处理方法相结合引入锚杆锚固质量无损检测中。通过在锚杆模型中的应用,发现该方法在确定锚杆锚固系统砂浆缺陷位置及大小有很好的效果。This paper, from development situation of nondestructive detection of the anchor- age quality, expounds the shortcomings of the existing bolt anchorage quality detection, points out the importance of anchoring system mortar plumpness degree detection, and combines innovatively the Hilbert transform and Wigner-Ville distribution signal processing method with the bolt anchoring quality nondestructive testing. Through the application of the bolt in the model, this method is effective to determine anchoring system mortar defect position and size.
