| Abstract: | A statistical damage softening constitutive model and the method of calculating parameters are developed based on Mohr-Coulomb criterion. And the theoretical relationship between the parameters and the characteristic vectors of rock failure curves is studied. Through some examples, the rationality and practicability of this model is validated. |

| Keywords: | rock failure micro-unit strength Weibull distribution Mohr-Coulomb criterion damage |
