Table 2 Meso parameters of parallel bonding model in numerical simulation test.
From: Shear strength deterioration effect of rock mass joint surface under cyclic shear load
Linear or parallel connection elastic modulus (GPa) | Linear or parallel bond stiffness ratio | Bonding distance/mm | Contact friction coefficient | Average contact tensile strength (MPa) | Standard deviation of contact tensile strength (MPa) | Standard deviation of contact cohesion (MPa) | Average value of contact cohesion (MPa) |
|---|---|---|---|---|---|---|---|
1.0 | 2.0 | 0.5 | 0.5 | 10 | 5 | 5 | 10 |
