Abstract: In order to study the effect of temperature difference on the mechanical properties of fractured rock mass under tensile-shear stress, the expression of fracture strength of single fractured rock mass under temperature difference was derived based on energy and linear elastic fracture mechanics theory from the phenomenon of rock mass tensile-shear failure in high rock temperature tunnels and slopes. The strength of fractured rock and the mechanism of crack growth and evolution under tensile and shear stress were systematically studied by combining the factors of fracture inclination, horizontal pressure and temperature stress with numerical method. The results showed that under tensile-shear stress conditions, as the temperature difference increasing from 5 ℃ to 15 ℃, the rock thermal expansion occured and the internal stress of fractured rock mass increased. When the fracture inclination angle was from 155° to the direction of the maximum shear stress of 180°, the main shear stress was easier to act on the fracture surface, which reduced the resistance to shear and the initial crack strength, thus promoted the fracture shear and spreaded. This study revealed the strength characteristics of single fissure rock mass under the condition of temperature difference influenced by many factors, which was helpful for engineers to make preliminary assessment of the stability of rock mass in the design stage, so as to formulate corresponding construction plans and preventive measures.

Key words: single fracture rock mass, temperature difference, fracture inclination angle, tensile-shear stress, initial crack strength
