Abstract: The bolt-resin interface is one of the common failure locations in resin anchorage systems and impairs the resin bolt's supporting effect on the surrounding rock of roadway to some extent. In view of the failure characteristics of the bolt-resin interface, a method for strengthening the anchorage performance of resin bolts by adding wire at the bolt-resin interface was established. The working principle of the method was elaborated in detail, and a combination of laboratory and field tests was used to analyze and verify its working characteristics and application effects. At the experimental scale, the results indicate that the anchorage method with adding wire can significantly improve the anchoring force per unit length of the bolt. When using this method for the same anchoring length, the bearing strength of the bolt anchorage system can be increased by approximately 79.6%, along with significant improvements in both anti-deformation failure capability and energy absorption performance. Considering the enhancement effects of bolt anchorage performance and the operation convenience of this method under different adding wire diameters, a reasonable wire diameter was determined to be 1.8 mm. Compared with the conventional measures of improving bolt performance by increasing the anchorage length, the proposed strengthening method proves relatively more effective. To achieve the same anchorage strength, this method can significantly reduce the required bolt anchorage length and save the amount of resin anchoring agent used. The field tests further verified the reinforcing effect of this method on the anchoring performance of bolts under on-site conditions and demonstrated its inhibitory effect on the attenuation of bolt performance during the support process. The study shows that the proposed anchoring performance enhancement method can effectively improve the comprehensive anchoring performance of resin bolts by modifying and strengthening the interaction between the bolt and resin at the interface, thereby providing.
