| Abstract: | Bolt has been used widely in geo-engineering all over the world in recent years,the testing technique of bolt develops quickly too.This paper summarizes simply the history of bolt testing technique, describes in detail stress wave reflection method. It is useful and valuable nondestructive testing method is verified with several parameters which estimate quality of bolting integrity. |
