Effects of Interface Damage Resulting from the Separation of Layered Strata on Bolt Anchoring Systems

Figure 12

Experimental results for the anchoring body with separation at different locations. (a) Relationship between pulling force and pulling displacement. (b) Relationship between the strain and distance along the bolt when the interface is in its original intact state and the separation is located in the middle, (c) the interface is partly damaged and the separation is located in the middle, and (d) the interface is partly damaged and the separation is located at the loading end.
