基于知识图谱的泡沫轻质土研究热点及发展趋势分析
Analysis of Research Hotspots and Development Trend of Lightweight Foam Soil Based on Knowledge Map

随着我国对可持续发展的重视度不断提高，在新型建筑材料中的应用逐步增多，以“泡沫轻质土”为主题词讨论“泡沫轻质土”的应用发展状况及目前研究现状，通过CiteSpace文献数据分析软件对2000~2023年CNKI中国知网上搜集到的494条文献数据进行可视化分析。结合CiteSpace分析出的图谱，研究结果表明：1) 泡沫轻质土研究领域经历了稳定–增长的发展阶段，泡沫轻质土领域引起国内学者重视较晚，但近10年研究处于稳步增长状态。2) 陈忠平、李洪亮、伊利华，刘勇，张留俊等学者是该领域的核心研究人员。天津市市政工程设计研究院是该领域的核心机构，广东盛瑞科技股份有限公司、中交第一公路勘察设计研究院有限公司和长安大学公路学院紧跟其后，发文量在10篇以上。就整体合作情况来看，每个机构彼此间都有合作关系，其中天津是市政工程设计研究院和多家公司有着合作关系。3) 最近几年的热点主要集中在“数值分析”、“铁路特征”、“动力特性”、“铁路路基”上，学者对泡沫轻质土特性的研究拓展其新的应用领域。本文旨在为读者清晰梳理泡沫轻质土近年来的知识脉络及研究成果，从而便于相关学者系统阐述该领域前沿热点及研究状况。
With the continuous improvement of China’s attention to sustainable development, the applica-tion of new building materials is gradually increasing. The application development status and current research status of “foam light soil” are discussed with “foam light soil” as the main topic. Through the CiteSpace literature data analysis software, the 494 literature data collected by CNKI from 2000 to 2023 were visualized and analyzed. Combined with the atlas analyzed by CiteSpace, the research results show that 1) the research field of foamed light soil has experienced a development stage of stability-growth, and the field of foamed light soil has attracted the attention of domestic scholars late, but the research has been in a steady growth state in the past 10 years. 2) Chen Zhongping, Li Hongliang, Yi Lihua, Liu Yong, Zhang Liujun and other scholars are the core researchers in this field. Tianjin Municipal Engineering Design and Research Institute is the core institution in this field, followed by Guangdong Shengrui Technology Co., LTD., China Communications First Highway Survey and Design Research Institute Co., LTD., and Highway College of Chang’an University, with more than 10 papers. In terms of overall cooperation, each institution has a cooperative relationship with each other, among which Tianjin Municipal Engineering Design and Research Institute has a cooperative relationship with a number of companies. 3) In recent years, the hot spots mainly focus on “numerical analysis”, “railway characteristics”, “dynamic characteristics” and “railway roadbed”, and scholars have expanded their new application fields by studying the characteristics of foamed light soil. This paper aims to clarify the knowledge context and research results of foam lightweight soil in recent years for readers, so as to facilitate relevant scholars to systematically describe the frontier hot spots and research status in this field.
