隧道火灾研究的知识图谱分析

为了解隧道火灾研究领域的整体情况,绘制隧道火灾科学的知识图谱,本文基于2000-2018年Web of Science和CNKI刊载的隧道火灾论文,利用VOSviewer技术,对隧道火灾科学进行全面可视化分析图谱显示,国际上隧道火灾研究的核心主题是Simulation、Tunnel Ventilation Temperature and Smoke、Tunnel Fire Safety,国内是数值模拟、隧道救援与疏散、隧道的消防灭火、火灾探测报警、隧道结构;高产的作者是Ji Jie和徐志胜等,近期活跃的作者是Zhang Shaogang和石晓龙等;开展隧道火灾研究的国家多位于欧洲。结果表明隧道火灾研究领域的发文量、主题分布及作者间的合作都已初具规模,国内更偏重于工程应用的研究,主题演变略快于国外,我国在此领域处于核心地位。

Knowledge Map of Tunnel Fire Research

In this paper,in order to perform a systematical overview of global characteristics of tunnel fire and draw a knowledge map of tunnel fire science,a comprehensive visual analysis of tunnel fire science was conducted based on the papers focusing on tunnel fire published in Web of Science and CNKI from 2000-2018 by means of VOSviewer. Overall distribution and evolution of tunnel fire themes were studied through keywords cooccurrence patterns and high-yielding authors. The recently active authors of tunnel fire science were studied through author cooperation network map,high-yielding authors and the number of national papers. The knowledge mapping shows that the hot topics of the international tunnel fire researches are simulation、tunnel ventilation temperature and smoke,tunnel fire safety,while those of domestic researches are mainly simulation,tunnel rescue and evacuation,fire-fighting,fire detection and alarm,tunnel structure. Ji Jie and Xu Zhisheng are the most prolific authors,Zhang Shaogang and Shi Xiaolong are the authors who have been active recently. Most of the countries carrying out tunnel fire research are in Europe. The results show that the volume of publications,the distribution of themes and the cooperation between authors in the field of tunnel fire research have begun to take shape. Domestic research is more focusing on engineering application and research theme evolves faster than international ones,and China is at the core of this field.
