摘 要:结合对保护对象燃烧特性的深入分析,通过建筑断面和设备布置的有序管控,有效减小火灾发生几率和降低蔓延危害。系统分析了特殊实验环境下科学装置的火灾特点,探究了现有消防灭火技术和设施的适用性及局限性。通过管控建筑布置、危险设备和燃烧物,减小火灾发生几率和降低火灾蔓延风险,确定了采用较为适合的探火管灭火装置进行重点防护的消防手段。通过研究隧道内火灾源分布、燃烧物特性、火灾危险性等情况,借助层次分析法(AHP法)确定了重点防护范围,为实际工程提供理论依据。Combined with the in-depth analysis of the combustion characteristics of the protected objects,the chance of fire occurrence and risk of fire spread can be effectively reduced through orderly control and management of the building section and equipment arrangement.The fire characteristics of scientific installations in the special environment are systematically analyzed,and the applicability and limitations of existing fire-fighting techniques and facilities are explored.The suitable extinguishing device with fire detection tube is determined for key protection.Through management and control of building layout,hazardous equipment and combustion materials,the chance of fire occurrence and the risk of fire spread can be reduced.Based on the study of the distribution of fire sources,characteristics of combustion materials,fire hazards in the tunnel,the key protection scope is determined by the Analytic Hierarchy Process(AHP),providing a theoretical basis for the actual project.
