摘要(Abstract):
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。
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 sr to Leckie's equation, and different models are put for to Leckie's equation, and different models are put ford according to rock mass containing drd according to rock mass containing dt volume of porosity.
