摘要： 为了还原一起电动自行车火灾的发展过程，对其人员伤亡原因进行分析研究。依据案例实际情况利用PyroSim 等软件构建了着火建筑模型，通过设置控制器进行数值模拟，得到了建筑物内火势发展、亡人房间内温度和一氧化碳浓度变化等情况。通过与实际火场照片进行对比，验证了起火点与关键位置的火灾发展情况，同时结合切片情况从温度、一氧化碳浓度和FED三个角度对亡人原因是高温与一氧化碳中毒的共同作用做出了合理的解释，为火灾调查工作提供了依据.

Abstract:

In order to reconstruct the fire development process of an electric bicycle fire and analyze the cause of casualties, according to the actual situation of the fire scene, the fire building model was built by using PyroSim and other software. Controllers were set for numerical simulation to obtain the fire spread velocity of the building, temperature and carbon monoxide concentration in the room of the dead. The fire development at the point of origin and the key position were verified by comparison with the fire scene photographs. Combining the slices from three angles of temperature, death was caused by the combination of high temperature and carbon monoxide was confirmed by carbon monoxide concentration and FED data. This research makes a reasonable explanation for the death cause, and provides basis for fire investigation.
