State-of-the-art: computational model for soil-interface-structure system

摘要: 土与结构的相互作用是水利和土木工程的一个关键共性问题,其分析是揭示工程中结构损伤破坏机理的重要环节。将土-界面-结构作为一个体系进行整体分析是精细研究土-结构相互作用的基础,但在大型工程应用时面临着一系列难题,包括：土-结构接触边界约束,土-结构接触力学特性,以及土-界面-结构体系建模和分析等。本文对这些问题的相关研究进行了综述和总结,并对今后的主要发展方向提出了建议。

Abstract: The interaction between soil and structure is a common problem in geotechnical engineering, which plays a key role in assessing the damage behavior of structure. The computational model for soil-interface-structure system is the foundation of the detailed study of the interaction between soil and structure, but it has to solve a series of problems, including soil-structure contact constraint and contact judgment, soil-structure mechanical behavior and constitutive model, and grid model for soil-interface-structure system, etc. The progress of the computational model for soil-interface-structure system is summarized, and a suggestion of its main developing trend is put forward.
