| 中文摘要: |
| 依据岩土类材料的非匀质性特性，并采用对材料参数进行随机赋值的方法研制了弹塑性破裂过程数值分析程序，并用实例证明了程序的可靠性。应用该程序对岩石试样弹塑性破裂过程进行数值模拟研究．分析表明：数值模拟结果与试验研究结果是吻合的。从而为工程岩体断裂分析提出了一种可能的方法与途径。 |
| 英文摘要: |
| The heterogeneity of rock-like materials is summarized in this paper. According to this property, a program for elastic|plastic failure process analysis is developed by means of the random assignment of material parameters, and several examples are put forward to prove the correctness and the reliability of this program. The elastic|plastic failure process of rock specimen was simulated by using this program, which demonstrates that the numerical results agree well with experimental results. The proposed method is applicable to analyze the elastic|plastic failure process of rock|masses in engineering. |
