Research on the bearing characteristics and parameter optimization design of variable-section anchor rods
Udgivet 2025-09-01Få fuldtekstUnder the influence of load transfer mechanisms in the surrounding rock-resin anchorage structure, conventional rock bolts exhibit limited utilization of steel tensile capacity due to insufficient axial force at their tail sections. To address the material waste caused by mismatch between anchor rod...
