Table 5
Statistics of the creep parameters of the red sandstone under the failure load level.
| Red sandstone’s state | Failure load (kN) | Duration of the damage phase (h) | Instantaneous strain rate (h−1) | Average creep strain rate (10−2 ∗ h−1) |
| Dry state | 35 | 11.8 | 0.936 | 0.308 | Wet state | 35 | 11.2 | 0.744 | 0.882 | 3 dry-wet cycles | 30 | 9.8 | 3.372 | 3.249 | 6 dry-wet cycles | 25 | 9.1 | 1.452 | 2.788 | 9 dry-wet cycles | 25 | 7.9 | 1.572 | 4.173 |
