| 摘 要： | 从系统的观点出发，采用热力学和协同学的基本理论和方法研究岩石受栽条件下的损伤演化问题。应用协同学的绝热消去法得到了岩石考虑初始损伤条件下的非线性力学模型；研究岩石破坏过程中的相变问题，并加以深入分析，获得了岩石受我破坏过程中裂纹的平均取向规律，揭示了岩石破坏过程申的声发射现象和体征规律；初步建立了岩石协同破坏理论框架，并应用数值模拟验证了理论分析的正确性。 |

| Abstract: | From the viewpoint of system,the problem of damage evolving process of rocks under the condition of stress was studied by means of the basic theory and method of thermodynamics and synergetics.The nonlinear mechanical model of rock considering its original damage was obtained by employing the adiabatic elimination method of the synergetics.The phase transition in the damage process of rock was studied and its deep analysis was also made and the average orientation laws of rock in the damage process were got... |
