| Abstract: | Adopting the acoustic wave detection device and applying the principle of reflection energy and phase variation of the audiofrequency stress wave at different wave impedance surfaces, the authors made nondestructive tests for qualities of rooibolts and anchors in tunnels, and investigated the detection technique. The results show that the adoption of the stress wave to the nondestructive detection of roofbolt and anchor qualities has enriched the techniques for detection of anchor qualities in tunnel wall rocks, and can better guarantee the quality of tunnel engineering construction. |
| Keywords: | rooibolt quality nondestructive detection audio-frequency stress wave reflection method |
