In order to analyze the research hotspots and frontier trends in the safety risk management of urban gas pipelines,with the help of CiteSpace and VOSviewer,the in-depth analysis wasconducted on the number of published papers,research cooperation,distribution of core authorsand research trends of the Chinese and Englishliterature sampledata by using the bib-liometrics method,and the future research directions were also prospected. The results show that in recent years,the research attention in the field of risk management of urban gas pipelines has gradually increased,and the number of published papers has shown an upward trend. The research hotspots mainly focus on the construction of risk assessment models,the determina-tion of risk acceptability criteria,the risk control strategies and the quantitative simulation analysis of risks,etc. The future re-search trend is expected to focus on the safety management of confined spaces,risk control technologies and quantitative risk assessment technologies. Therefore,it is recommended to build a failure database ofurban gas pipelines in China,develop the clustering methods for risk assessment units,and conduct the research on the risk management of hydrogen-blended gas pipe-lines,multi-factor optimal risk control decision-making technologies,etc. The researchresults can provide reference for re-searchers to conductresearch on risk management of urban gas pipelines.
