Non-linear analysis of soil structure interaction problem is still an active field of research due to development of useful interface element between the soil–soil and soil–structure. In this paper a focused review on coupled finite element modeling of soil structure interaction (SSI) system with soil non-linearity and interface element modeling is discussed. The non-linearity in soil is reviewed with various available constitutive models, whereas the Interface modeling is reviewed with zero thickness and thin layer elements, which is proposed by many researchers from 1970 to till date with special emphasis on behavior of superstructure. Further the paper discusses on the occurrence of ill conditioning due to significance of interface thickness and selection of normal and tangential stiffness during interface modeling. In addition to above, some special interface element (different degree of freedom on top and bottom face of element) in non-linear SSI is also reviewed. Therefore the attention is on advantages and disadvantages of the discussed methods according to their applicability, accuracy and caliber to idealize the superstructure and soil.

由于在土壤-土壤与土壤-结构之间建立了有用的界面元素，对土壤结构相互作用问题的非线性分析仍然是一个活跃的研究领域。本文重点讨论了土壤结构相互作用（SSI）系统与土壤非线性的耦合有限元建模和界面元建模。用各种可用的本构模型对土壤中的非线性进行了综述，而用零厚度和薄层单元对界面建模进行了综述，这是许多研究人员从1970年至今提出的，其中特别强调了上层建筑的行为。此外，本文还讨论了由于界面厚度的重要性以及界面建模过程中法向和切向刚度的选择而导致的不良条件的发生。除了以上 还回顾了非线性SSI中的一些特殊界面元素（元素顶部和底部的自由度不同）。因此，应根据所讨论方法的适用性，准确性和口径，对理想化上部结构和土壤的方法的优缺点进行关注。
