摘要
针对当前工程锚杆中施工可能存在质量问题及检测中存在的技术问题,通过12根工程试验锚杆及50根PVC管模型锚杆的测试,以达到以下4个目的:锚杆随龄期、注浆孔大小、锚杆杆体直径的波形及波速变化情况;锚杆中存在1个、2个、3个缺陷时的波形特征;缺陷处于不同位置时的波形特征;建立模型库。
In view of the quality problems in current bolt construction and technical problems in bolt quality testing,four goals are achieved with 12 engineering testing bolts and 50 PVC pipe model bolts:Waveform and the wave velocity changes with bolt age period,size of grouting hole and bolt diameter; waveform characteristics in bolts which have 1,2 or 3 defects; Waveform characteristics in bolts which have defects in different position; The establishment of model library.
