随着我国寒区建筑、铁路、公路、管道等重点工程项目的大规模修建,从技术角度要求冻土与结构物共同工作体系具有良好的变形协调条件,以保证工程建(构)筑物长期工作性能,其中冻土-结构接触面特性直接影响系统的共同工作性能。从自身研究实践和对国内外该领域研究成果出发,从试验仪器、影响因素、微观结构以及本构模型方面,分别对冻土-结构接触面特性的主要研究成果进行了系统总结,分析了研究现状和存在的问题。结合对研究思路和方法论的探讨,构建了冻土-结构接触面特性研究的思路框架,提出了冻土-结构接触面研究的主要内容和方向,以期明晰研究重点和难点,理清研究思路,为该领域的深入研究提供借鉴和参考。
With the large-scale construction of key construction projects such as construction, railways, highways, and pipelines in cold regions in China, the joint working system of permafrost and structures is required from the technical point of view to have good conditions of deformation coordination to ensure the long-term construction of buildings. Work performance, in which the characteristics of the frozen soil-structure contact surface directly affect the system’s working performance. Based on its own research practice and research results in the field at home and abroad, the main research results of frozen soil-structure contact surfaces were systematically summarized from the aspects of experimental instruments, influencing factors, microstructures, and constitutive models, and the research was analyzed. The status quo and existing problems. Based on the discussion of research ideas and methodology, the framework of the study on the characteristics of permafrost-structure interface was constructed, and the main contents and directions of the study of permafrost-structure interface were proposed to clarify the research focus and difficulties and clarify the research ideas. For the in-depth research in this area to provide reference and reference.
