Creep Characteristics of Different Saturated States of Red Sandstone after Freeze-Thaw Cycles

Table 6

Creep parameters of specimens under failure stress.

Saturation	Failure stress (MPa)	Creep time (h)	Decelerated creep stage	Stable creep stage	Accelerated creep stage
			Initial creep rate	Steady-state creep rate	Accelerated creep rate
30%	16.74	0.96
50%	13.05	5.33
70%	9.46	2.73
90%	8.20	12.74
100%	4.61	25.59
