摘　　要：为研究西藏高海拔条件对古建筑火灾的影响,分别在拉萨与廊坊进行了中等规模木垛燃烧实验。测得了木垛燃烧的质量损失速率、火焰高度和燃烧温度,并分析了空气中氧气含量和大气压力对木垛引燃和燃烧的影响。实验表明:在拉萨低气压条件下,木垛引燃难度加大、燃烧时间增加、质量损失速率降低、木垛中心温度降低。The combustion experiments of medium size wood crib were conducted in Lhasa and Langfang,for investigating the influence of high altitude on fires burnt in ancient buildings in Tibetan.The mass loss rate,fire height and combustion temperature were measured.The effect of oxygen quantity and the atmosphere on ignition and combustion of wood crib were analyzed.The results show that the hardness of wood crib ignition was augmented,the combustion time was increased,the mass loss rate was reduced,the temperature of wood crib center was reduced.

关 键 词：西藏古建筑 低气压 木垛 质量损失速率 燃烧温度
