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

Figure 11

Experimental facilities and detailed parameters for the uniaxial bolt tension test. (a) Loading system and data acquisition facilities. (b) Detailed parameters for the steel cylinder and cross section of anchoring body; note that I represents separation occurring in the middle of the anchoring body, for which ten strain gauges were installed; II represents separation occurring at the free loading end, for which eleven strain gauges were installed; and III shows the cross-sectional dimensions of the specimen.
