The role of anchor rod

Anchor rod is a rod system structure reinforced by rock and soil. Through the longitudinal tensile force of the anchor rod body, the shortcoming that the tensile capacity of the rock and soil mass is far lower than the compressive capacity is overcome.

On the surface, it seems to restrict the separation of rock and soil bodies from the original body.

From a macro perspective, it increases the cohesion of the rock and soil mass.

From a mechanical point of view, anchor rod mainly improves the cohesion C and internal friction angle φ of the surrounding rock mass.

In essence, the anchor bolt is located in the rock and soil body and forms a new complex with the rock and soil body. The anchor rods in this complex are the key to solving the low tensile capacity of the surrounding rock mass. As a result, the bearing capacity of the rock and soil itself is greatly enhanced.

Anchor rods are the most basic component of tunnel support in contemporary underground mining mines. They bind the surrounding rock of the tunnel together so that the surrounding rock itself supports itself.

Anchor rods are now used not only in mines, but also in engineering technology to actively reinforce slopes, tunnels, dams, etc.
