bergförstärkningar
Bergförstärkningar, or rock reinforcements, are measures taken to stabilize and strengthen rock masses, typically in underground excavations like tunnels, mines, and caverns, or on steep slopes. The primary goal is to prevent rockfalls, ensure structural integrity, and create a safe working or passage environment. These reinforcements work by increasing the overall strength and stability of the rock mass, often by interlocking unstable blocks, supporting loose material, or improving the load-bearing capacity of the rock.
Common methods of bergförstärkningar include rock bolts, which are steel rods drilled into the rock and anchored
