锚杆锚固的无损检测日益成为地下岩土工程亟需解决的一个重要课题。目前业界普遍使用声波法无损检测技术,而该技术的效果不佳。本文首先介绍了弹性波无损检测的基本原理,然后通过模型实验对比,取得了一定的结论,可以作为锚杆锚固弹性波无损检测技术提供一定的理论依据。
The non-destructive testing of bolt anchorage is increasingly becoming an important issue for underground geotechnical engineering. At present, the non-destructive testing technology of acoustic wave is widely used in the industry, and the effect of this technology is not good. This paper first introduces the basic principles of non-destructive testing of elastic waves, and then obtains some conclusions through comparison of model experiments. It can provide a theoretical basis for the non-destructive testing of anchorage elastic waves.
