| Abstract: |
| In this paper,on the basis of hypothesis that the distribution of rock microelement strength complies with Weibull distribution,the relation between the dimension of defects of rock material and its damage evolution is investigated with the conception of dimension in fractal theory,the physical meaning of dimension Df in the relation is analyzed as well as the constitutive law of rock material based on the relation is illustrated with two examples. |
