摘要：

Bolt has been used widely in geoengineering 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. Fully grouted bolt has a fast develop and wide use in building engineering such as mining, traffic, foundation support, dam foundation and highwall now[1].Common bolt anchoring inspect methods are pulling method and drilling method.Which are destructive, operating-complex and expensive.So it is an emergent project for research of nondestructive-anchoring inspects technique.
