TL;DR: In this article, a series of uniaxial and triaxial compression tests were conducted to investigate the influence of freeze-thaw cycles on the mechanical properties of biotite granite in cold regions.

TL;DR: In this paper, the authors focused on the bond strength of cemented concrete-rock joints and showed that the shear strength of joints with good adhesion is strongly dependent on the strength of the cohesive interfaces when applied normal stress is less than 6 MPa.

TL;DR: In this article, a temperature field model was developed to show the influence of airflow on the temperature of the surrounding rock in a cold region tunnel, and a numerical analysis method was used to discuss the temperature field change law of surrounding rock and the thermal insulation measures of the Galongla tunnel.

TL;DR: According to the basic law of water flow and heat transfer in porous media under freeze/thaw condition, based on the theories of continuum mechanics, thermodynamics and segregation potential, the governing equations for thermo-hydro coupling model are established as mentioned in this paper.

TL;DR: In this paper, the authors determined the effective stress coefficient of coal during gas penetration and investigated the impact of effective stress and gas slippage on coal permeability under cyclic loading conditions.
