对不同位置、不同缺陷长度锚杆锚固体系模型进行了室内试验，探讨了检测锚杆锚固质量时波的传播规律，指出对于有缺陷的锚杆锚固体系，波形在缺陷位置处出现畸形，变得不规则，并呈现出缓慢衰减态势；对于缺陷位置不同的锚杆，测试曲线表现出不同的波形特征。
對不同位置、不同缺陷長度錨桿錨固體繫模型進行瞭室內試驗，探討瞭檢測錨桿錨固質量時波的傳播規律，指齣對于有缺陷的錨桿錨固體繫，波形在缺陷位置處齣現畸形，變得不規則，併呈現齣緩慢衰減態勢；對于缺陷位置不同的錨桿，測試麯線錶現齣不同的波形特徵。

Models of different location and defective anchor bolts of different lengths are tested to study the rules of stress wave propagation in the anchoring body when stress wave nondestructive method is used to detect the anchorage quality. For the defective anchor bolts,the wave at defec-tive location is distorted with an irregular wave attenuating slowly. The testing curves of acceleration response signal at bolt head exhibit different waveform characteristics when the defective location is different.
