Sensitivity Analysis in the Estimation of Mechanical Parameters of Engineering Rock Mass Based on the Hoek–Brown Criterion

Table 6

The comparison between the simulated and observed EDZ and displacement.

	EDZ (m)		Displacement (mm)
	RK-320-0-1	RK-320-0-2	M1-1	M1-2	M2-2	M2-3
Actual	3.4	1.8	29.5	28.9	23.1	20.5
Simulation	3.1	1.5	24.5	20.6	20.5	17.4

Note: the actual displacement of point M2-1 is not effectively recorded.
