| Abstract: | This paper is to study the non linear properties of rocks on uniaxial loading on the basis of the non linear theory and damage mechanics. According to the analysis of non elastic strain of rocks, a secant modulus method was established to construct the damage constitutive equation of rock, and the correctness of this model was verified via computer modeling of stochastic rock failure and analyzing the stability of slope. |
