摘　　要：地下建筑的防火设计相较于一般建筑而言有一定的特殊性。基于地下建筑火灾的特性,对其防火设计的安全目标和基本要求进行了梳理,详细分析了地下建筑空间的防火排烟系统和地下建筑空间亚安全区的设计。另外,就防火涂料的应用进行了深入的探讨,详细介绍了膨胀型防火涂料和水基防火涂料的特点和应用场合。研究结果表明:地下建筑的防火设计对于建筑的安全至关重要,科学的防火设计和合理选择防火涂料可以显著提高地下建筑的防火安全性。The fire prevention design of underground buildings has certain particularities compared with that of general buildings.Based on the characteristics of fires in underground buildings,the safety objectives and basic requirements of their fire prevention design are sorted out.The fire prevention and smoke exhaust system of the underground building space and the design of the sub-safe area in the underground building space are analyzed in detail.In addition,the application of fireproof coatings is deeply discussed,and the characteristics and application scenarios of intumescent fireproof coatings and water-based fireproof coatings are introduced in detail.The results show that the fire prevention design of underground buildings is crucial to the safety of the buildings,and scientific fire prevention design and the selection of fireproof coatings can significantly improve the fire prevention safety of underground buildings.
