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。

关 键 词:接触面  单剪试验  数值模拟  刚塑性模型

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.
Keywords:interfaces  simple shear test  numerical simulation  rigid-plastic model
