摘　　要：分析影响公路隧道火灾灭火及冷却供水强度的主要因素。根据近年来国内外的部分公路隧道汽车火灾实验数据,以及热平衡模型,计算不同规模火灾的灭火供水强度、泡沫供给强度和冷却供水强度。结果表明,小型、中型和大型公路隧道火灾的理论供水强度分别为0.35、0.40、1.20L/(s·m2);隧道顶部衬砌的理论冷却强度为0.20L/(s·m2),实际冷却强度为0.40L/(s·m2)。The main factors affecting the highway tunnel fire ex tinguishing and cooling agent supply intensity were analyzed. According to the experimental data of highway tunnel fire in China and other countries, and thermal equilibrium model, the extinguishing water supply intensity, foam supply intensity and cooling agent supply intensity for different fire scale were calcu late＆ Results showed that the theoretical intensity of small, medium and large fire is 0. 35,0. 40,1. 20 L/（s . m^2 ） ; The the oretical cooling intensity of tunnel top lining is 0. 20 L/（s .m^2）, while the actual cooling intensity is 0.40 L/（s.m^2）.
