摘要 将计算机数值模拟技术应用于火灾再现,采用FDS(Fire Dynamics Simulator)软件对一起建筑火灾事故进行再现研究.根据火灾现场勘查报告和现场照片建立了仿真模型,根据数值模拟得到的火势发展、温度变化和通风条件,分析了受火建筑各区域的燃烧程度.由分析结果与火灾现场勘查笔录比对的吻合程度,验证了模拟结果的合理性,从而旁证了起火点判断的合理度. Computer numerical simulation method was applied to fire investigation and a building fire was reconstructed using FDS（Fire Dynamics Simulator） software. A computer model was established based on the fire investigation report and photographs. Then, with the fire spread, temperature and wind conditions from the simulation results, burning degree of each zone in the building was analyzed. The agreement of the analyze result and fire site investigation report showed that the numerical simulation was reasonable, therefore, the conjecture of ignition source was reasonable.
