Anchor bolts have a wide range of applications. Firstly, in mining operations, they serve as the core support for the roof and side walls of underground tunnels and working faces, effectively preventing roof falls and rib failures. Secondly, in tunnel and underground engineering, anchor bolts, in conjunction with shotcrete, form the primary support system to control rock mass deformation, constituting a key technology in New Austrian Tunneling Method (NATM) construction. Furthermore, anchor bolts play an irreplaceable role in slope stabilisation, deep excavation shoring, and the stabilisation of dam foundations and reservoir banks in water conservancy and hydropower projects. Finally, anchor bolt technology is indispensable in construction projects for anti-floatation anchors, foundation reinforcement, and the addition of storeys to existing buildings. In summary, by applying active or passive anchoring forces to rock and soil masses, anchor bolts extensively ensure the safety and stability of various geotechnical engineering projects.
