In order to study the mechanical properties of NPR anchor cable under static tension and drop hammer impact load, The self-developed NPR anchor cable tension test system and NPR anchor cable drop hammer impact test system were used to conduct static tensile test and dynamic impact test for a certain batch of NPR anchor cables. Its resistance to and absorption of slow deformation and instantaneous impact energy of surrounding rock are verified by the supporting force, elongation and expansion of anchor cable. Secondly, a 3D numerical model of NPR anchor cable is established, and relevant numerical parameters are calibrated according to laboratory test results. The static tensile test of NPR anchor cable and the drop hammer impact test are carried out. The results of the numerical test are in good agreement with those of the laboratory test, which verifies the reliability of the numerical model. The 3D numerical model of NPR anchor cable can be used as an auxiliary analysis tool for the improvement and upgrading of NPR anchor cable in the future.
