Volume Changes and Mechanical Properties of Expansive Mudstone below Canals under Wet-Dry/Wet-Dry-Freeze-Thaw Cycles

Table 2

Saturation variations of sample during the WD/WDFT processes.

Processes	Wet	Dry	Freeze	Thaw
	Si	St	St	St
Sample		30% (dry range I)	30%	30%
Saturation	100%	70% (dry range II)	70%	70%
		90% (dry range III)	90%	90%
Remarks	In the dry process, different St means different dry ranges. Among them, dry range I represents that St is 30%; dry range II represents that St is 70%; dry range III represents that St is 90%.
