土石坝渗流领域基于图谱可视化分析研究

Study on Visualization Analysis Based on Atlas in Seepage Field of Earth Rock Dam

为了分析当今土石坝渗流领域的发展趋势及目前研究热点问题,以“土石坝渗流”为主题词,通过citespacV分析软件对2001~2021年CNKI中国知网的搜集到的737条文献数据进行可视化分析。研究结果表明:1) 目前国内关于土石坝渗流的研究方向相较于较早年份有较大进展,虽然总体发文量数量较早年出现增长,但是在最近几年发文数量有所下降。2) 以刘贤鹏,余正源,包腾飞,丁倩,刘得俊,岑威钧等为中心发表了大量的学科文献,而紧随其后的作者发文量为7~19次,除此之外,大部分作者都是发文量仅在1~4次,说明研究土石坝渗流领域的作者众多,但就研究作者和机构之间联系密度还不够。3) 通过关键词共现图谱,结合词频,中心度,聚类等分析,“渗流稳定”、“坝坡稳定”、“侵润线”、“稳定分析”、“稳定性”等为近几年的研究热点;就此观察可以得出目前前沿的关于土石坝渗流的领域是关于“渗流稳定”方向的学习。本文研究结果可以为读者清晰梳理土石坝渗流研究近年来的研究成果及研究热点,并追溯土石坝渗流演化进程,从而为相关学者追踪该领域近期热点及未来发展趋势提供参考。

In order to analyze the development trend and current research status of seepage field of earth-rock dam, this paper uses “seepage of earth-rock dam” as the main topic and uses citespacV analysis software to carry out visual analysis of 737 literature data collected by CNKI from 2001 to 2021. The results show that: 1) The current research direction of seepage flow of earth-rock DAMS in China has made great progress compared with that in the early years. Although the overall number of published papers has increased compared with that in the early years, the number of published papers has decreased in recent years. 2) With Liu Xianpeng, are the source, take-off, minny, liu jun, as the center, published a lot of subjects such as wei-jun cen literature, and followed by the author is identificated 7~19 times, in addition, most of the authors are identificated only in 1~4 times, author shows that the research in the field of earth dam seepage is numerous, but the study authors and institutions link between density is not enough. 3) Based on keywords co-occurrence atlas, word frequency, centrality and clustering analysis, “seepage stability”, “dam slope stability”, “intrusion line”, “stability analysis” and “stability” have become research hotspots in recent years. From this observation, it can be concluded that the current frontier field about seepage of earth-rock dam is about the study of “seepage stability” direction. The research results of this paper can clearly sort out the research achievements and hot spots of seepage research on earth-rock DAMS in recent years, and trace the seepage evolution process of earth-rock DAMS, so as to provide reference for relevant scholars to track the recent hot spots and future development trend of this field.
