Abstract：Random non-homogeneous solid-thermal-coupled mathematics model and FEM are used. In plane stain state，the influence of heterogeneity on crack propagation in granite is studied with thermal dilatability and thermal conduction of exponential distribution and Weibull distribution based on a lot of numerical experiments. The relationships among the type of the random distribution，distribution parameter，time and thermal cracking of granite samples are pointed out.
