Research For Mechanical Character And Dynamic Testing Property Of Fully Grouted Bolt

On the basis of analysis for past research outcomes , using many comprehensive methods such as laboratory experiment and theoretical analysis , connecting the theory of the neutral point about full-length grout bolt ,the paper further studies the traveling wave regulation of rock bolt under function of working load .Firstly, the paper describes the traveling wave regulation of elastic stick, then based on it, the wave spreading law of rock bolt in the different restricted state is studied. In theory, the consolidating wave speed is intervenient the inherent wave speed of bolt and of the anchor media. Moreover, the consolidating wave speed inherent in the material of the reinforcing bolt and the anchor media, and it relates to the cling strength of bolt and the anchor media.Secondly, based on large quantity of documentations research and analysis, In the situation of different anchorage length ,transfer mode,...
