摘　　要：基于火灾烈度理论,采用实验的方法确定了石膏板受热痕迹的预测模型,与FDS源代码相耦合,实现了重现石膏板受热痕迹的功能。进行了较为接近真实火灾的火灾场景实验,记录火灾发展的情况和火场温度的变化。利用增加了新功能的FDS软件对火灾场景实验进行了数值重构,通过对比火场温度、热释放速率和火灾后石膏板壁面留下的痕迹,验证了数值重构的有效性,证明了对痕迹进行数值重构能够对火灾调查工作起到辅助作用。Based on the theory of fire severity, the predicting model of heated trace of gypsum board was identified by fire ex- periment,combined with FDS source code, heated trace of gyp- sum board was reconstructed by FDS. And,a fire scene experi- ment was conducted,fire development and temperature change were recorded. Using FDS of new function, numerical recon- struction on fire experiment was made, by comparing tempera- ture,HRR and trace of gypsum board after fire, the effective- ness of numerical reconstruction was proved, and numerical re- construction on trace was proved to be assistant for fire investi- gation,
