Abstract

Abstract

In order to study the relations among the constant resistance value of sliding anchor bolts with expanded heads and the anchor bolt sizes, the elastoplastic theoretical formula was deduced based on the elastic theory for the constant resistance of large deformation bolts, which could be suitable to predict the constant resistance values of sliding auchor bolts with expanded heads. The numerical simulation software was researched the constant resistance values in five working conditions, and the simulation results of the three working conditions were contrasted with the results from indoor experiments, and the results showed that the numerical simulation model had less differences from the experimental results, and the model was more reasonable; the theoretical resistance values calculated by the elastoplastic theoretical formula were in good agreement with the ones by numerical simulations.
