| description | Abstract In order to improve the elongation and impact-resistant mechanical properties of FRP anchors, an energy-absorbing FRP anchor consisting of a FRP rod body, a tail connector, a tray, an energy-absorbing sleeve, an enlarged round table and a nut is designed innovatively. The combination of theoretical analysis, experimental research and numerical simulation is used to study its impact resistance mechanical properties, and the supporting effect is verified by on-site industrial test methods. The following conclusions are mainly drawn: (1) In the process of static tension, the elongation of energy-absorbing FRP anchors is 3.65 times higher than that of conventional FRP anchors, and the energy-absorbing energy is 5.4 times higher than that of conventional FRP anchors. (2) Under different impact energies, the breaking displacement, elongation and energy absorption of energy-absorbing FRP anchors are 3.86 times, 3.86 times and 5.76 times that of conventional FRP anchors, respectively. Under different impact velocities, the average elongation of energy-absorbing FRP anchors is 4.24 times that of conventional FRP anchors, and the average energy absorption is 5.55 times that of conventional FRP anchors, indicating that energy-absorbing FRP anchors have better impact resistance. (3) After the energy-absorbing FRP bolt is used in the 31,204 working face of the No. 2 mining area of Narin River, the support state is stable, and the bolt is broken and the support failure does not occur. The field application results show that the energy-absorbing FRP anchor has good impact mechanical properties. |
