| 摘 要： | 提出了用有限元一无界元的方法计算地下结构——土耦合体系的应力和变形。为了模拟实际受力状态，在地下结构与土相接触的界面上设置了一种有厚度的接触面单元，它可以与土体的弹塑性模型相衔接，能合理地反映接触面及其邻近区域剪切破坏带中的变形性状。

| Abstract: | In this paper, the method of the finite-infinite element is suggested to calculate the stress and deformation of coupling systems of structure-soil. In order to simulate the actual situation, a new kind of inter face element with thickness is installed in the interface between soil and structure. It can dovetail with elastic-plastic models of soils, and can reflect the deformation in the interface and its nearby shear failure area reasonably. The investigation is valuable for the design and construction of underground structure. |
