Shear strength of joint with different lithologies.
| | Joint surface type | Low-strength rock mass | High-strength rock mass | | Peak strength (MPa) | Growth rate (%) | Peak strength (MPa) | Growth rate (%) |
| | Smooth joint | 2.83 | | 3.17 | | | JRC 0~2 | 3.38 | 19.43 | 3.98 | 25.56 | | JRC 4~6 | 3.72 | 31.45 | 4.43 | 39.75 | | JRC 8~10 | 4.20 | 48.41 | 5.34 | 68.45 | | JRC 12~14 | 4.88 | 72.44 | 6.02 | 89.91 | | JRC 16~18 | 5.78 | 104.24 | 6.97 | 119.87 |
