通过分析北京奥运会主火炬燃烧对体育场钢结构、ETFE(乙烯-四氯乙烯共聚物)膜材料和对火炬塔本身的影响,提出钢结构安全评价标准和ETFE膜结构安全评价标准。针对主火炬的燃烧影响,提出了主火炬塔消防安全设计与审核方法,并对火炬塔施工及赛时的消防安全,提出了具体的落实措施。 By analyzing the impact of the main torch combustion of the Beijing Olympic Games on the stadium steel structure, ETFE (ethylene-tetrachlorethylene copolymer) membrane material and the impact on the torch tower itself, the steel structure safety evaluation criteria and ETFE membrane structure safety evaluation criteria are proposed. In view of the influence of the main torch’s combustion, the fire safety design and audit method of the main torch tower are put forward. Concrete measures are also put forward for the construction of the torch tower and the fire safety during the race.
