In view of the failure characteristics and the special requirements of bolts used in bump-prone roadways, the energy-absorption anchor(cable) is invented. The energy absorption principle of the energy-absorption anchor(cable) is analyzed based on the plastic bending theory, and the static tension and impact tension tests are carried out by use of the independently designed static and dynamic loading test system. The test results show that the hex pipe of energy absorption anchor(cable) is squeezed and defor...
