摘要
建立了用于描述隧道内火灾事故污染物的一维扩散模型。并用此模型对公路隧道火灾事故在短时间内污染物的流态进行了数值模拟和分析。通过模拟分析结果和实验统计结果的对比 ,表明了模型的可行性。最后 ,给出了污染物浓度计算公式 ,以供参考。
A one-dimensional contamination diffusion model for tunnel fire is presented. Based on this model, a highway tunnel fire within a short time course was simulated and analyzed. Compared to the test results, the simulation result demonstrates that the model is feasible. In the end, it suggests a formula for highway tunnel fire contamination. The author hopes that this analysis will be available as the foundation of highway tunnel fire control.
