摘　　要：城市地下综合交通枢纽是一个客流高度密集、多种设备系统共存、多重交通工具中转的空间,一旦出现灾害,很可能会酿成重大安全事故。火灾是城市地下综合交通枢纽的最主要灾害。本文在分析火灾诱因的基础上,对消防的难点以及关键技术进行探讨,并对城市地下综合交通枢纽火灾研究方法以及研究现状进行综述,指出了城市地下综合交通枢纽消防未来研究的发展方向。研究表明:对于现有的城市地下综合交通枢纽,考虑到运行、费用等因素,采用数值模拟技术结合局部现场试验是研究火灾烟气扩散合理可行的手段,多点火源的火灾场景问题应予以考虑并引入相关防排烟系统设计。开展火灾非线性系统演化、火灾羽流复杂的时空行为研究将有益于消防设计。Urban underground comprehensive transportation hub is a space of high concentration of passenger flow,coexistence of many equipment systems and multi-modes of transport transition.It would lead to server incidents,once disaster happens.Among different kinds of disaster,fire is the most important disaster.Based on analyzing the fire incentives,difficulties and key technologies in fire prevention are investigated.The research methods and current status are reviewed and future research directions are put forward.The results show that numerical simulation combined with local field tests is a practical way to study fire smoke propagation according to operation feasibility,costs and other factors for existing urban underground comprehensive transportation hub.However,fire scenario of multi-point ignition sources should be considered and introduced in related design.It would do good to fire prevention design that we do research in the fields of fire non-linear system elevation and complex time-space character of fir plume.
