Abstract
In order to analyze the temperature distribution law in rough fissured rock mass more truly, the fractal dimension of fractal theory is used to make statistics on the roughness of fissured surface, and a heat flow coupling theoretical model considering the fractal characteristics of fissured surface of rock mass is established. By building a geometric model containing rough fissured surface and numerical simulation by software, the more real temperature distribution law in rough fissured rock mass is analyzed. The simulation results show that the temperature distribution in rough fissured rock mass appears channeling phenomenon, and convection plays a leading role in the temperature distribution, and the existence of fissured seepage leads to a relatively low temperature zone in the rock mass.
