| 中文摘要: |
| 在地下工程的数值模拟过程中,合理地模拟岩土体的本构关系是非常重要的.对大型有限元计算分析软件Marc进行了二次开发,介绍了如何在Marc中施加土体的Duncan-Chang非线性弹性模型和岩体的Drucker-Prager弹塑性模型.并通过工程实例表明文中所述方法是合理可行的. |
| 英文摘要: |
| The reasonable constitutive relations of rock-soil mass is very important in the process of numerical simulation of underground engineering. The large software of Marc about finite element is secondly developed. The realization methods about Duncan-Chang nonlinear elastic model and Drucker-Prager elasto-plastic model are described. The engineering example shows that the methods are right and reasonable. |
