In this study

precast concrete blocks

#45 steel screw

mine chemical grout were used to simulate the surrounding rock and bolt. Shear tests of bolted jointed rock specimens were carried out to study characteristics of jointed shear stress and the cable deformation under three conditions of no-anchored

end-anchored and full-anchored specimens. The results show that obvious differences were found in curves of shear-jointed rock displacement with various anchoring ways. The no-anchor specimen was characterized as brittle. For the end-anchored specimen

a turning point was found in the slightly decreased shear when adjusting the shear strength of anchor. Compared with the above two specimens

the best matching was achieved by the full-anchored specimen with the joint

which indicates that the bolted specimen could bear the greatest shear force. For both the end-anchored bolt and the full-anchor bolt

their deformation characteristics can be divided into the tensile zone

shear-tension zone and compression zone. Under the combined action of shear and tension

the failure of the anchored bolt occurred in the shear-tension zone. With different anchorage modes

the distribution of axial force varied as well during the shear test. The axial force of full-anchored bolt was mainly distributed in the vicinity of the joint. Moreover

it decreased rapidly with the increase of the joint distance. While the distribution of axial force was relatively uniform in the end-anchored bolt.
