Experimental Study on Shear Behavior and Failure Mechanism of Bolted Heterogeneous Rock Joints under Different Anchorage Conditions

Table 1

Peak shear strength of rough rock-like joints under different anchorage conditions.

JRC 4 ~ 6	3.87	5.02	5.83
JRC 8 ~ 10	4.63	5.69	6.35
JRC 12~14	5.27	6.68	7.22
JRC 16~18	6.31	7.81	8.65
