摘　　要：本文从细观力学角度，分析了尾砂胶结充填体的物理组成，单轴压缩时的破坏机理，并运用损伤力学方法建立了其本构方程。结果表明，理论曲线与实验曲线吻合得较好。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.
