| 摘 要： | 完成了两种散粒体间接触面的单剪试验，对试验过程进行了有限元数值模拟，对比了刚塑性、理想弹塑性和Clough-Duncan接触面本构模型对计算结果的影响，并分析了计算模型的破坏过程。计算取得了与试验基本一致的接触面破坏规律。结果表明，用刚塑性模型描述两种散粒体间接触面的本构关系是合理的。

| Abstract: | Simple shear tests for the soil-soil interface are conducted；and numerical simulation is performed to model the testing process. The different interface constitutive models, such as rigid-plastic, elastoplastic and Clough-Duncan nonlinear elastic models, are used in the numerical analysis; and the failure mode of interfaces is investigated. The calculation results agree well with the test results; and it is shown that the rigid-plastic model is suitable to describe the soil-soil interface. |
