Table 4

Comparison of safety factor interval and statistical law of actual dump.

Fuzzy linguistic value	a = 0.51
	Membership interval	Safety factor interval
Stable	{1}		22/22
Basically stable	[0.653, 1]	[1.093, 1.21)	4/9
Critical	[0.316, 0.653]	[1.03, 1.093)	3/7
Basically unstable	[0, 0.316]	[0.92, 1.03)	1/6
Unstable	{0}	[0, 0.92)	0/4
