摘要 根据滑移型裂纹模型,基于裂纹扩展过程中的能量平衡原理,建立了三轴压缩情况下岩石材料的变形模型,并模拟了围压为20,50,80 MPa时花岗岩的变形特征。研究结果表明,模拟结果与实验结果符合得比较好,为通过裂纹模型定量研究岩石材料在三轴压缩情况下的变形特征提供了一种可行方法。 Based on the sliding crack model and the energy balance during crack growth, the deformation properties of the granite under triaxial compression are simulated at the confining pressures of 20, 50 and 80 MPa respectively. It is shown that the simulated results agree well with the experimental results. The work in the paper can present an available method to quantitatively analyze the deformation properties of rock material under triaxial compression by using crack model.
