摘　　要：通过定性和定量相结合的方法,研究了CNG加气站储气井泄漏所产生的燃烧爆炸事故后果影响。先采用事件树分析法定性分析出CNG加气站储气井天然气发生泄漏时可能发生的事故后果;再运ALDHA软件建立数学模型,并重点针对燃烧爆炸事故危害后果进行数值模拟定量分析,得出直观图表;最后通过图表分析,可得出危害半径。该方法可以对CNG加气站的安全管理、事故应急救援以及新建加气站提供技术支持。This paper studies the consequences of combustion explosion accidents caused by leakage of gas storage wells in CNG gas stations with qualitative and quantitive methods.Firstly,the paper qualitatively analyzes possible consequences of gas storage well leakage in CNG gas station by Event Tree Analysis（ETA）,then creates a numerical model to conduct quantitative analysis,focusing on the simulation analysis of the consequences by using the ALOHA software,and obtains the intuitive charts.Through the chart analysis,the paper may provide the technical support to security management of gas stations,accident emergency rescue as well as the new filling stations.
