| Abstract: | Based on meso scopic mechanics,this paper analyses physic components of cemented tailing filling and fracture mechanism when conducting uniaxial compression.By using the method of damage mechanics,the constitutive equation is established.It is found that the theoretical curve coincide with the experiment curve well. |
