基于CiteSpace的隧道火灾研究进展及展望

Research Progress and Prospect of Tunnel Fire Based on CiteSpace Analysis

为了全面探究隧道火灾的研究进展,基于中国知网和Web of Science核心合集数据库,运用Cite Space文献计量软件,以2000~2022年隧道火灾文献为数据基础,分别从发文量、关键词聚类、发文机构和学者、研究热点及趋势等方面进行可视化分析,并对未来发展进行展望。结果表明:1)隧道火灾领域发文数量呈上升趋势,并在2014年以后增长迅速。国内学者发文量占比较高,国际影响力逐渐增强。2)隧道火灾研究方向主要包括“数值模拟”“通风排烟”“烟气温度”“应急疏散”等内容。中国科学技术大学、中南大学、瑞典RISE研究所等高校和科研院所是研究主力,但研究团队之间合作交流较少。3)随着隧道种类日益复杂,“隧道坡度”“大气压强”“分岔隧道”等成为研究热点。4)未来,可将人工智能、大数据等技术运用到相关研究中,加强学科交叉融合和学术交流合作,完善法律法规,提升行业影响力。

To study the research progress of tunnel fire comprehensively,visual analysis is conducted on literature temporal distribution,keyword clustering,research institutions and scholars,research hotspots,and frontier trend of papers related to tunnel fire from 2000 to 2022 based on CNKI and core collection database of Web of Science,and using CiteSpace analytic tool.Findings are as follows:(1)The overall volume of publications in the field of tunnel fire has shown an increasing trend and grows rapidly after 2014.Chinese scholars take the leading position in this field and receive widespread influence across the world.(2)The main research topics include numerical simulation,ventilation and smoke extraction,smoke temperature,and emergency evacuation.Prominent research institutions such as University of Science and Technology of China,Central South University,and RISE Research Institutes of Sweden and their scholars are main research forces.However,the collaboration and communication among research teams is relatively small.(3)With the increasing complexity of tunnel types,the frontier hotspots gradually focus on tunnel slopes,ambient pressure,and bifurcated tunnels.(4)For future research,with the help of artificial intelligence,big data,and other emerging technologies,interdisciplinary integration and academic cooperation can be further strengthened.Laws and regulations in tunnel fire should be improved and revised to enhance international status.
