Mechanical properties of anchor bolt (cable) action and yield experiment

Based on anchor bolt (cable) mechanism and analysis of the action of anchor bolt (cable) on rocks mechanical effects, the paper studied the force and deformation characteristics of anchor bolt (cable), explored the feasibility of the use of the disc tray combination for yield supporting on bolting supporting.Under high stress, large deformation and impact load, the bolt capacity is not affected in the premise of ensuring that supporting body had certain deformation, through release of some stress, bolt breaking was reduced and avoided, effectively improving bolt support effect.
