| (b) Obtained stress-strain of saturated rock sample |
| (c) Stress-strain under 2 times of freeze-thaw cycle |
| (d) Stress-strain under 4 times of freeze-thaw cycle |
| (e) Stress-strain under 8 times of freeze-thaw cycle |
| (f) Stress-strain under 16 times of freeze-thaw cycle |
| (g) Stress-strain under 24 times of freeze-thaw cycle |
