| 摘 要： | 从岩体合大量做裂隙的情况出发，考虑岩石的变形初始非线性及其破坏以前的变形特征，建立了类似于Leckie等人形式的损伤演变方程，并根据岩体所含孔隙度的不同提出了不同的模型。

| Abstract: | In this paper, considering the initial nowhnearity about deformation of rock anddefortnatinn charactffi of rock before it is destroyed, a damage evolution equation about rockmass colltaining a lot of micro-back is built, Which is s~r to Leckie's equation, and different models are put fo~rd according to rock mass containing d~t volume of porosity. |
