| 摘 要： | 研究表明，土体小应变特性对准确预测土体的变形起着十分重要的作用，而这一特性很难用传统的本构模型对它加以描述。边界面模型能描述一些经典塑性理论所不能描述的土的真实特性，如何将之进一步加以改进，并有效地应用于土体小应变特性的模拟中是一个有待深入研究的课题。

| Abstract: | It’s shown by research that the soil’s small strain feature is very important to predict soil’s deformation, this feature is difficaltly to be described by those traditional constitutive model. The boundary model can describe some real feature that can’t be described by traditional plastic theory. How to make more improvement and use it to research soil’s small strain feature is a problem deserving further research.. |

| Keywords: | boundary model soil small strain constitutive model |
