Mesoparameter Calibration and Macro-Mesoparameter Correlation of Tailing Sand

Table 3

Rate of change of macromechanical parameters affected by changes in mesoparameters.

Macromechanical parameters	Mesoparameters
			pebble-fric	wall-fric
Cohesion	86.15% (4)	251.80% (1)	99.33% (3)	148.43% (2)
Internal friction angle	2.39% (4)	6.40% (2)	40.11% (1)	3.16% (3)
Peak principal stress	6.10% (3)	6.62% (2)	115.97% (1)	5.97% (4)
Peak corresponding strain	46.91% (1)	3.44% (3)	0.69% (4)	3.55% (2)

Note: the units in the table are the absolute values of the rate of change of each macroparameter. The values in parentheses represent the ranking of influence degree.
