摘　　要：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。Most detection on anchorage quality stay in the step of using fluid pressure operated jacks.This paper adopted non-destructive method to detect anchorage quality of rock bolts at underground powerhouse in BaiSe water conservancy project and used wavelet analysis to transfer the signals.According to analyzing the composed wave and the original wave,it is indicated that using the wavelet analysis which is mentioned in this paper to analyze wave could evaluate anchorage quality more efficiently.
