基于文献计量学的土壤固化剂研究进展与热点分析

Research Progress and Hot Spot Analysis of Soil Stabilizer Based on Bibliometrics

为了探索近40年来“土壤固化剂”研究领域的发展状况、热门观点及研究进展,基于文献计量学,检索和筛选中国知网数据库(CNKI)中从1983-2023年收录的关于“土壤固化剂”研究的文献数据,协同VOSviewer可视化软件对文献数据进行统计分析。分析结果表明:经过筛选共分析文献766篇,40年来论文产出演化进程分为萌芽阶段、发展阶段、深化阶段;主要研究机构为西北农林科技大学、长安大学等,其中水利部水土保持生态工程技术研究中心的高建恩团队、中国地质大学的项伟团队、西北农林科技大学的樊恒辉团队发文量较高;发文量较多的期刊分别为北方交通、交通世界,而被引量较高的期刊为岩土力学;国内该领域以土壤固化剂的研究为主,衡量指标以无侧限抗压强度为主,以“土壤固化剂”、“固化剂”、“无侧限抗压强度”为代表的关键词分别出现346次、126次、90次;土壤固化剂领域内出现频次≥5的热点关键词组有效聚类分为4个聚类群,聚类标签分别为土壤固化剂、固化剂、无侧限抗压强度、固化机理;主题演化分析显示,生态友好、高效可行的土壤加固技术为当下最活跃的研究领域,深入土木工程、土壤科学、土壤物理学以及材料科学等领域交叉融合是未来土壤固化剂研究发展的方向。未来在土壤机理深入研究及绿色环保固化技术、高效固化剂开发、一体化固化技术等方面将成为研究热点,致力于不断寻找绿色高效的固化剂,达到提高固化土壤的效果和速度。

To explore the development status,popular viewpoints and research situation of the research field of"soil stabilizer"in the past 40 years.Based on bibliometrics,the literature data on the study of"soil stabilizer"collected from 1983 to 2023 in China National Knowledge Infrastructure(CNKI)were retrieved and screened,and the literature data were statistically analyzed with VOS viewer visualization software.A total of 766 articles were analyzed after screening.In the past 40 years,the evolution process of paper output was divided into embryonic stage,development stage and deepening stage.The main research institutions are Northwest A&F University,Chang'an University,etc.Among them,the Gao Jian'en team of the Soil and Water Conservation Ecological Engineering Technology Research Center of the Ministry of Water Resources,the Xiang Wei team of China University of Geosciences,and the Fan Heng-hui team of Northwest A&F University have published a laige number of papers.The journals with the largest number of papers are Northern Transportation and Transportation World,while the journals with the largest number of citations are geotechnical mechanics.Domestic research in this field is mainly based on soil curing agent,and the measurement index is mainly based on unconfined compressive strength.The keywords represented by"soil curing agent","curing agent"and"unconfined compressive strength"appear 346 times,126 times and 90 times respectively;the effective clustering of hot key phrases with frequency≥5 in the field of soil curing agent is divided into four clustering groups,and the clustering labels are soil curing agent,curing agent,unconfined compressive strength and curing mechanism.The theme evolution analysis shows that eco-friendly,efficient and feasible soil reinforcement technology is the most active research field at present.In-depth integration of civil engineering,soil science,soil physics and material science are the direction of future research and development of soil curing agent.In the future,the research on soil mechanism,green curing technology,high efficient curing agent development and integrated curing technology will Income the hot spot,to improve the effect and speed of soil solidification.
