Fracture-pore networks and brittle with ductile stress-strain mechanisms: Triaxial tests on >7,600 m samples yield insights for 10,000-m deep sandstones
Key Points
Fracture-pore networks formed significant patterns in geomechanical testing, enhancing our understanding of deep sandstone behavior.
Key evidence from triaxial tests shows that both brittle and ductile mechanisms contribute to stress-strain responses in over 7,600-meter samples.
Analysis involved extensive triaxial tests on deep sandstone samples, captured key stress-strain mechanisms for excavation challenges.
Highlights the need for further investigation into the behavior of sandstone under extreme conditions to improve engineering applications.
