北京奥林匹克公园地下交通联系通道性能化防火设计研究

Performance-based Fire Safety Design of Underground Traffic Tunnel in Beijing Olympic Park

北京奥林匹克公园地下交通联系通道非常复杂,采用性能化防火设计方法有利于促进消防系统安全可靠、经济合理。本文对该通道的火灾危险性、纵向排烟设计、人员安全疏散、结构防火保护、火灾报警及自动灭火系统设计等进行了分析,提出了有效可行的解决方案和措施。该项目的研究成果已被某工程采纳,并可为其他城市隧道设计提供借鉴。

The underground tunnel system in Beijing Olympic Park involves very complicated design problems. For its fire protection system, there are no precedent standards, and similar projects both at home and abroad. A method of performance-based fire protection design is used to evaluate the security, reliability, rationality and economy of this system. Its fire risk, longitudinal smoke evacuation, people evacuation, structure fire protection, fire alarm and sprinkler system, etc. are all analyzed and validated carefully. Effective and feasible measures are adopted in this project. This study result can be a useful reference for the design of other related urban tunnels.
