地铁隧道空间狭长,行进列车内人员密集,且突发事故后不易逃生和救援,极易成为恐怖爆炸袭击的目标,而相关的规划设计、风险评估和应急响应尚不完善。基于此,结合中国现有地铁实际情况,借助有限元方法研究了地铁隧道内恐怖爆炸袭击破坏下的爆炸冲击波定量分布特征及人员伤亡区域分布特征,结合冲击波超压伤害准则建立了伤亡区域定量预测模型,并在此基础上从地铁隧道结构特征、地铁运行辅助系统等方面对此类恐怖袭击事件应急救援所面临的关键问题进行了剖析。研究成果将为地铁反恐怖防范提供必要的理论依据和技术支撑。
Subway tunnels are long and narrow, with heavy traffic in moving trains and difficult escape and rescue after a sudden accident, which can easily become the target of a terrorist attack. The relevant planning and design, risk assessment and emergency response are not yet complete. Based on this, combined with the actual situation of China’s existing metro, the quantitative distribution of explosive shock wave and the distribution of casualties in the subway tunnel were studied by means of finite element method. Quantitative prediction of casualty area was established based on the principle of shock wave overpressure injury Based on this, the key problems faced by emergency rescue of such terrorist attacks are analyzed from the characteristics of metro tunnel structure, subway operation support system and so on. The research results will provide the necessary theoretical basis and technical support for anti-terrorist subway.
