Nondestructive Technique for Qualities of Roofbolts and Anchors in Tunnel

This paper researched the anchor exploratory testing and discussed the testing techniques relying on the third-party quality inspection test center anchor exploratory test of de-shang highway. The results showed that as an adjunct to the project quality management, nondestructive testing with elastic wave enriched the quality of tunnel surrounding rock anchor testing methods and provided better quality assurance for the tunnel construction.
