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

<div>Comparison between the actual situations of excavation response and the prediction results simulated based on S-shaped criterion and SS criterion. (a) Displacement of surrounding rock at the location of extensometer M1-1 and M2-1. (b) The depth of EDZ along the direction of boreholes K0+320-0-1 and K0+320-0-2.</div>
