摘　　要：近年来城市地下燃气管道事故频发,在公共安全方面带来了诸多隐患。对中国公开报道的194起城市地下燃气管道事故案例进行了统计分析,揭示了事故致因、发生时间、空间分布和事故后果等四方面的发生规律,在此基础上总结了事故特征并进行了分析。分析结果表明:城市地下燃气管道首要事故致因为第三方施工破坏;事故数量大体呈现逐年增长的趋势,且具有一定的季节性,7~9月为事故高发期;华东地区作为中国经济发展相对迅速的地区,事故发生率也相对较高;重大事故和较大事故仅占约2%。在城市背景下,燃气管道事故会给公共安全带来巨大威胁,若未及时、妥善处置,可能演变为巨大灾难。研究成果有利于减少中国燃气管道事故及可能带来的损失。In recent years,there has been a significant increase in the frequency of urban underground gas pipeline incidents,which poses a serious threat to public safety.To gain a better understanding of the characteristics of these incidents,this study conducted a statistical analysis based on 194 publicly reported cases of urban underground gas pipeline incidents in China.The study reveals the occurrence patterns in four aspects:causes of incidents,occurrence time,spatial distribution,and consequences.Based on these findings,the characteristics of the incidents are summarized.The results of the analysis revealed that the primary cause of urban underground gas pipeline incidents is damage caused by third-party construction activities.The number of incidents shows a general increasing trend over the years and exhibits a certain seasonality,with the highest occurrence during the months of July to September.Furthermore,the region of East China,known for its rapid economic development,has a relatively higher incident rate compared to other areas in the country.However,it is important to note that major incidents and relatively large-scale incidents only account for approximately 2%of the total accidents recorded.This study highlights the significant threat that underground gas pipeline incidents pose to public safety.These incidents have the potential to escalate into catastrophic disasters if they are not properly addressed in a prompt manner.The research results are beneficial in reducing underground gas pipeline incidents and their associated losses in China.
