Research on A Dynamic Detection Technique for Anchorage Quality of the Anchor Bolt-Surroundings Rock System
Anchorage technology is applied widely to rock and civil engineering in order to strut, solidify the rock and control the stability of the rock. The use quantity of anchor bolt is enormous, reached 250 million per year at abroad, so the detection about the anchorage state is very important. We consider anchor bolt and its surrounding rock as a dynamic system in this paper, constitute the dynamic model of this system, and study the dynamic response in a transient shock load when the bolt is excited. Due to the systems dynamic model is a damping wave equation, it has different transient exciting response under different initial and boundary conditions, so the anchorage state of an anchor bolt can be recognized, and to realize the dynamic detection of the anchoring state.
