Loading schemes with different σ₃ at b = 0.

Time (min)	Effective confining pressure (kPa)	Loading scheme
240	50	The rigid loading plate and two flexible loading plane controls were used in the test. The horizontal loading plate was kept separate from the specimen, pressure was applied in the axial direction with strain control loading, ε1 was set as 25%, axial strain velocity was set as 0.21%/min, and the strain in the two horizontal flexible loading directions was the same
