To avoid the impact of inherent natural imperfections on experimentaloutcomes during testing, a recently designed genuine triaxial apparatus hasenabled the replication of conditions where the three principal stressesexhibit varying magnitudes. This setup facilitates the examination of fracturebehaviors in materials similar to the 4-series under genuine triaxial stressstates. The experimental findings revealed that the maximum strengthexperiences significant influence from the minimum principal stress and theintermediate principal stress in genuine triaxial stress conditions.Specifically, for a fixed minimum principal stress ({\sigma}3), there is aprogressive reduction in peak strain as the intermediate principal stress({\sigma}2) increases. Moreover, as the minimum principal stress ({\sigma}3)rises, the magnitude of peak strain diminishes. The Young's modulus of thespecimens exhibits an exponential increase with the augmentation of confiningpressure, and it demonstrates a linear growth pattern as the intermediateprincipal stress increases. Additionally, the cohesion force is observed torise while the internal friction angle decreases with the elevation of theintermediate principal stress. The failure modes of the specimens in genuinetriaxial stress conditions can be categorized into three types, all of whichexhibit a specific angle between the fracture surface and {\sigma}3, rangingfrom 50 to 62 degrees. Furthermore, a comparison between the computed range andthe actual measurement range of the fracture angle highlights severallimitations in the relationship between the fracture angle ({\theta}) and theinternal friction angle ({\phi}) within the Coulomb criterion, particularly inrocks containing complex fracture systems.
