英文摘要：
In the fields of civil engineering and earthquake engineering, soil and structure dynamic interaction is a research hotspot. It is very important to properly simulate the mechanical performance of soil-structure interface in the numerical analyses of soil and structure dynamic interaction. In this paper, some conclusions are drawn by analyzing the research status in this field. First, technical devices need to be developed and test technologies be improved so that the real mechanical state of Soil-Structure contact could be perfectly revealed. And then, the study on mechanical performances and failure mechanism could be deepened with the help of newly developed test technologies and new test results of Soil-Structure interfaces, in which emphasis should be laid on the rate-dependent mechanical characteristics. Finally, improvement of numerical simulation methods highlighted by the achievements mentioned above is now desirable and feasible. To sum up, all the three steps together form one of the future trends in the research of Soil-Structure dynamic contact.
