Abstract: Based on the theory of fracture mechanics, influence law of rock strength with
single fracture, a set of fracture and multiple sets of fractures under the action of temperature
stress caused by the temperature field higher than room temperature field is presented
quantitatively. In the view of theoretical point, starting from elasticity mechanics, using the
analytical method such as equivalent load method and principle of superposition, the thermal
stress expression of a single fracture is added to the structural load expression of a single
expression in representative volume element(REV). The micro-fracture strength expression of
intermittent fractured media, of which crack tip of rock fracture is affected by certain
temperature stress, is deduced. The microscale such as fracture length and fracture direction and
so on is combined effectively and organically with the macroconditions such as temperature and
strength. The strength expression of fractured rock at this stage has been improved. A
exploration of new idea which could demonstrate the macro-, micro-levels and consider
