| The non-interpenetrated jointed rock is a common terrain, both the realm of engineering and the realm of theory pay great attentions to its mechanics performance. The experiment (Chen Yunsheng, 2001)of non-interpenetraed jointed media by using CT is simulated by FEM in this paper. The paper is consisted of the analysis of the gray-scale of the middle section, the analysis of the crack and crush of the middle section, the analysis of meso-damage isoline of the middle section and the analysis of the effects of the varied material parameters to the meso-damage and crack in the last. The gray-scale analysis of the model of the experiment by using CT is analyzed by the probability design. A bank of material parameters is selected by comparing the average gray-scale analysis with the result of experiment. Comparing the result of calculation of crack, meso-damage and gray-scale with the result of the experiment respectively. The stage-like characters are all found in these processes of simulating. What's more, the effects of varied material parameters to the meso-damage and crack are preliminarily stated in this paper. The varied material parameters contain Young's modulus, Poisson's ratio, Shrcf-op, Shrcf-cl, Untensst. The curve of each material parameter and the function of each curve are listed in this paper also. The results may be valuable in the field in the future.
