| 摘 要： | 据岩体在卸荷情况下的拉剪应力状态,确定了节理岩体的线弹性断裂力学模型。依照此模型,可以得到相对远离裂隙(该位置的点到裂隙中心的距离比裂缝长度大)且受裂隙影响区域内应力、应变和变形方程。这些对评估裂隙岩石变形有重要的参考意义。通过用理论方程的计算结果和卸荷情况下试验观测所得的数据对比,证明该模型应用于实际工程中具有可行性。 |

| Abstract: | Under tension and shear conditions related to unloading of rock mass,a linear elastic fracture mechanics model of jointed rock mass is established.According to the model,the equations of stresses,strains and displacements of the region influenced by the crack but relatively far away the crack(the distance between the research point and the center of the crack is longer than the length of crack)are derived.They are important for evaluating the deformation of cracked rock.It is demonstrated by the comparison between computational results of these theoretical equations and the observed data from unloading test that this model are applicable for actual engineering. |
| Keywords: | jointed rock mass unloading fracture mechanics mechanic behavior rock mass model |
