Parameter unidentifiability in Hoek–Brown calibration under sparse triaxial datasets: a bootstrap-based diagnostic framework

Abstract The Hoek–Brown criterion is widely used for rock-mass strength characterization; however, its material constant m i is often calibrated from limited triaxial datasets without formal uncertainty quantification. This study shows that such calibrations can be practically no...
