Rock Reinforcement:
- The rock reinforcement systems to stabilize tunnels, surface, underground mines, and mine roadways intersections are designed using Factor of Safety (FoS), which is a ratio of the reinforcement resistance to the roof rock-load of overlying immediate strata.
The following applications of rock reinforcement are mentioned below:
- Rock reinforcement (rock anchor) is used to anchor suspension cables and guy wires to bridges.
- To strengthen (provide additional stability) the rock mass internally by increasing its resistance to shear stress and sliding along fractures.
- Rock anchors can be used to support sheet piles.
- Uplift due to lateral forces in transmission towers, foundations, and hydraulic structures is resisted by rock reinforcement.
- It helps to tie down the wire cables with the foundation under the sea.
- Rock reinforcement is used to pre-load the foundation.
