摘要
震后起火是国外几次大震的普遍现象。本文通过对国外几次震后火灾的对比分析，归纳总结了引发震后火灾的主要因素及震后火灾的特点。震后火灾与生命线系统的破坏有密切关系，本文从震后火灾的机理出发，提出了用事件树模型预测供气、供电系统引发震后火灾的方法．
Fire following earthquake is a significant feature of each seismic event. Based on the study of several post-earthqauke fires in Japan and America, the main causes of igniting post-earthquake fire are summed up. There is a close relationship between post-earthquake fire and urban lifeline system.In this paper, grounded on the mechanism of igniting post-earthquake fire, the authors propose an event tree method to predict post-earthquake fire ignited by failure of urban electric power supply system and gas supply system.
