基于知识图谱的砂卵石地层可视化研究及趋势分析

Visualization Research and Trend Analysis of Sandy Pebble Stratum Based on Knowledge Graph

为了解当前砂卵石地层学科的发展动向和当前的研究状况,以“砂卵石地层”为主题,利用CiteSpace文档分析软件,对CNKI在1965~2023年间收集到的465篇文献资料进行了可视化分析。研究发现:1) 砂卵石地层的研究经历了三个时期,即发展停滞期、稳定发展期和快速发展期,这一领域受到了学者们的关注,但是这一领域的研究正处在一个快速发展的时期。2) 何川、袁大军、方勇、晏启祥、白永学、漆泰岳等学者是该领域的核心研究人员,其发文频次均在6以上;西南交通大学交通隧道工程教育部重点实验室和北京交通大学该领域内的核心机构,领域内各机构目前已形成较为成熟的合作关系网络。3) “砂卵石”、“盾构”、“数值模拟”、“盾构隧道”是最近几年主要的研究热点关键词,相关学者已经对此进行了大量的研究。本文能够帮助读者更好地梳理国内外砂卵石地层研究的研究热点和研究最新进展,同时也能追溯砂卵石地层研究领域的发展过程,为相关学者跟踪这一领域的最新热点和未来发展趋势提供借鉴。

In order to understand the current development trend and current research status of the sand and gravel geotechnical discipline, we used CiteSpace document analysis software to visualize and analyze 465 documents collected by CNKI from 1965 to 2023. It was found that: 1) The research on sandy pebble stratum has gone through three periods, i.e., the period of stagnant development, stable development and rapid development, and this field has received attention from scholars, but the research in this field is in a period of rapid development. 2) He Chuan, Yuan Dajun, Fang Yong, Yan Qixiang, Bai Yongxue, and Chia Taiyue are the core researchers in this field, and the frequency of their publications is above 6. Southwest Jiaotong University Key Laboratory of the Ministry of Education for Traffic Tunnel Engineering and Beijing Jiaotong University are the core institutions in this field, and the institutions in the field have formed a more mature cooperative relationship network at present. 3) The terms “sand cobble”, “shield”, “numerical simulation” and “shield tunnel” have been the main research hot words in recent years. This paper can help the reader to better understand the terms “sand cobble”, “shield”, “numerical simulation” and “shield tunnel”. This paper can help readers to better understand the latest progress and hotspots of sandy pebble stratum research at home and abroad, and also trace the development of sandy pebble stratum research, so as to provide reference for scholars to follow the latest hotspots and future development trends in this field.
