Reliable determination of the Hoek brown Mi parameter in brittle rocks using the maximum secant modulus criterion in multistage triaxial test

Abstract Accurate estimation of the Hoek–Brown material constant (mi) is essential for reliable rock mass characterization, particularly in brittle, heterogeneous carbonate formations. This study introduces an optimized multi-stage triaxial compression test (ML-TCT) using a maximum secant modulus (E...
