锚杆锚固质量及受力状态的检测目前大多停留在利用液压千斤顶进行破坏性拉拔试验的阶段,文中采用无损检测的方法对百色水利枢纽工程地下厂房主变岩锚杆锚固质量进行检测,应用小波分析对实测信号进行分解及重构,通过对重构前后的波形进行分析比较,研究表明采用文中所述方法对波形进行处理比原始波形能更有效地反映锚杆锚固状况,评价锚固质量。 At present, most of the testing of bolt anchoring quality and stress state remain in the stage of destructive pull test by using hydraulic jacks. In this paper, the anchoring quality of main anchoring rock bolts of underground powerhouse of Baise Project is tested by non-destructive test. Wavelet analysis of the measured signal decomposition and reconstruction, by analyzing the waveform before and after reconstruction, research shows that the use of the method described in the waveform processing than the original waveform can reflect the anchor more effectively anchor the situation, evaluate the quality of the anchor.
