摘要： 根据一起挖掘机配件仓库亡人火灾的调查情况，利用FDS 进行数值模拟重构，将模型中可燃物烧毁情况和现场勘察图片进行分析比对，并获取模型中热释放率、温度和气体浓度参数的变化规律；最后假设火场按标准采取喷淋措施进行分析对比。模拟结果表明，模型中可燃物烧毁情况符合现场勘察结果；亡人的卫生间温度和CO 气体浓度均达到危险值，推断高温灼烧和烟气中毒窒息的共同作用是造成亡人的主要原因。当模型中采取喷淋措施，能有效降低火场温度与CO 浓度。

Abstract: According to the investigation of a death-causing fire in an excavator parts warehouse, FDS was used to carry out numerical simulation and reconstruction. The burning situation of combustibles in the model was compared with the on-site investigation pictures. The heat release rate, temperature and gas concentration in the model were obtained. Assuming that water sprinkler was used, the data were analyzed and compared. Simulation results showed that the burning situation of combustibles in the model agreed well with the results of the on-site investigation. The temperature and the volume fraction of CO in the toilet where the deceased was located reached dangerous values. As the result, the main causes of death could be the joint action of high temperature burning, smoke poisoning and suffocation. If water sprinkler were used, the temperature and the volume fraction of CO concentration would be effectively reduced.

Key words: FDS, warehouse fire, burning situation, fire investigation
