山区软基础土工格栅应用研究热点及发展趋势分析

Application Research Hotspot and Development Trend Analysis of Soft Foundation Geogrids in Mountain Area

摘要: 土工格栅是土工合成材料的一种，常用作加筋土结构的筋材或复合材料的筋材等，因此土工格栅的研究变得尤为重要，为探索其演化发展，为后续学者的研究提供思路与启发。基于CiteSpace可视化分析软件以“土工格栅”为主题对2008~2023年中国知网的826篇文献进行分析。结果表明历年来文献发表数量总体呈下降趋势；研究此领域的作者团体较少，研究学者较为分散；研究机构前几名大多都为高校，且机构间的合作交流较少；土工格栅、拉拔试验、路基、沉降是当前此领域研究热点方向。最后在文献研读和分析的基础上，就土工格栅领域的以后研究做出了预测并提出了几点建议，以供后续学者参考。

Abstract: Geogrid is a kind of geosynthetics, which is often used as reinforcement of reinforced earth structures or composite materials, etc. Therefore, the research of geogrid becomes particularly important to explore its evolution and development, and provide ideas and inspiration for subsequent scholars’ research. Based on CiteSpace visual analysis software, 826 documents of CNKI from 2008 to 2023 were analyzed under the theme of “geogrid”. The results show that the number of published documents has declined over the years; There are few author groups studying this field, and the researchers are scattered; Most of the top research institutions are colleges and universities, and there are few cooperation and exchanges between institutions; Geogrid, pull-out test, subgrade and settlement are the current research hotspots in this field. Finally, on the basis of literature study and analysis, this paper makes predictions and puts forward some suggestions for the future research in the field of geogrids for the reference of subsequent scholars.
