Implication

Experimental tests reveal temperature impacts on mechanical properties and failure modes of sandstone, indicating stability concerns in geothermal tunnels.

Key Points

Strength of sandstone changes with temperature, first increasing and then decreasing, demonstrating a relationship between temperature and failure modes.
Scanning electron microscopy shows how microstructure alterations influence mechanical properties with temperature variations.
Coupling tests were performed, indicating that permeability decreases initially before increasing, reflecting complex thermal-hydraulic-mechanical interactions.
Findings underscore the significance of thermal effects on rock stability, particularly in geothermal tunnel environments.
